An 18-year-old Pleasanton man was taken into custody while appearing in court this morning to answer to felony charges relating to the June 9 collision on Foothill Road that killed Diana Hersevoort, 58, of Dublin. 

Cody Matthew Hall walked into the courthouse with a smile on his face, drinking a sports drink and leaned against the wall, surrounded by friends as he waited for court this morning. Just before the doors were opened for court, Hall's demeanor changed slightly and he appeared nervous. 

As Hall stood in front of the court, Judge Hugh Walker ordered that he be immediately taken into custody and held in a "no bail status" after the Alameda District Attorney's Office increased the charge of felony vehicular manslaughter in the death of Diana Hersevoort to murder. Hall has also been charged with felony reckless driving.

Timothy Rein, Hall's lawyer, has not yet been reached for comment.

Hall will be held at the Santa Rita Jail in Dublin until his next court appearance. 
During his first court appearance on July 29, Hall was ordered by Judge Walker not to drive during the course of the case.

On June 9, Hall is believed to have been passing a vehicle on Foothill Road at about 83 miles per hour, when he lost control of his car, striking bicyclists Diana and Joe Hersevoort, according to documents submitted by police to the court.

Hall surrendered to police on July 26 and was booked at the Santa Rita Jail in Dublin. Hall had been free on $100,000 bail. Read the full story here.

Protective custody -- what a laugh. Even the hard core criminals are apparently a threat to this loser. If they have him in protective custody to protect him from himself then turn him loose. Save all of us the cost of a trial and lifetime incarceration because that's exactly where this sociopath is headed.

Hi my name is Jamie and Diana was a mom to me. So of the comments are nice and some are others opinions ill stay away from the drama. The positive people thank you. I'm 30 years old I have known Diana and her family as her daughters were my two best friends since I was 14 years old. It hurts I want her back I have woken up and think wow what a bad dream I have to call mom aka Diana and tell her this... But I can't. I can't comfort my 2nd family like they need. But what made me say something is that when we found out an 18 year old kid hit mom we pulled back our hate and said he will live with this the rest of his life! Then it turned into hurt and I'm guessing that does not go away! But THEN we read postings on Facebook we read how he wreked cars and was speeding and doing drugs.. Maybe not all on that day. But truth came out! If he wasn't passing a car at 83 mph... Would he not of hit mom on her favorite blue beach cruiser and killed her. I don't know?? :( but he has had a various past of driving problems! I also want to say something about protective custody! A person gets that either if the prison feels he needs it or if he got hurt or threatened by another inmate or if he requests it. It is lock down in so many words and it will not change if that's the truth. Who cares at this point someone broke the law and in sure he is scared or has a big heart or is a good kid.. He broke the law. Now pay the price anyone would have too. I don't care what happens to Cody at all.. I care about my friends and family. Justice might be served but you can't mend our broken hearts.. The smell of Diana when you walk in the door and her husbands aka joe face and disposition. 58 years old on a bike ride with the one you love for a fun day turned out so tragic. :(

Nobody has to like everyones opinion but you should respect others even if it is not your view. Nobody should be telling anyone to shut up. Express yourself respectfully!

I was in the front row and watched as Judge Walker called up Cody Hall and read the new charge: MURDER. I didn't see Cody's father (only know what he looks like from a mug shot though). Cody or his friends didn't show any sympathy towards us (Diana's family), but I got a close up view of Cody crying when they put the handcuffs on. On Monday when he returns, he'll be in jumpsuit, instead of the black suit he wore on Wednesday. I plan to be there again . . . and hope to hear Judge Walker say NO BAIL
JoAnne Norman August 16, 2013 at 01:20 PM
I know there have been many posts stating negative and positive things about the Hall's. But all Diana's family really has to go on is their actions, and nobody representing the Hall's has extended sympathy or remorse to Joe or their daughters.

I have said some very harsh things about Cody hall and his father. I probably have not said them very tactfully because this situation disgusts and infuriates me. Some have accused me of being insensitive and yes...I am. I have no filters. I think this situation infuriates me more than anything else...not because i have a personal vendetta against Cody or his Dad, but because it is the product of the culture of Pleasanton parents or a significant minority within. Aaron was raised an entitlement brat in the mid to late 80's by a section of baby boomer parents that were more interested in being their kids friend than parent. When he did get into trouble, its my opinion they were too busy being the "cool parents" to really drop the hammer on him. Pain teaches people, and Aaron never learned it. Its my opinion that his upbringing amongst suburban brats that turned their noses up at a place like Dublin and called it the "wrong side of the tracks" or "ghetto" that produced a lot of his past and current issues. Cody, being raised by someone so flippantly taught nothing could do little more than repeat and worsen those behaviors as a big portion of the Pleasanton folks from Aaron's generation really seemed to think they were something special. They were. A lot of them were entitlement brats like him. The world owed them something for converting oxygen into carbon dioxide when they really offered little back other than knowing where to shop and the best curbside cafe's in town. FHS did not graduate generation of losers. The same problems and idiotic parenting existed and exists at AHS. This is a cultural issue with this community and needs to be looked at as one or we will continue to plant trees in high schools and pull kids bone fragments from utility poles on Foothill Rd. Our adults in Pleasanton need to drop the Hammer. A judge is about to do what they wouldn't. that's a fact and a symptom. the Hall family has been destroyed by this I'm sure. It's very hard to feel sorry for them when they have displayed a lot of disregard for the life lost, the law and the weight of the situation in general until it was basically stuffed up their noses. The victims family has been forever fractured. Diana was erased by the reckless, boastful, "nothing bad ever happens to me" dogma that seems to permeate Pleasanton youths. Those that survive without killing themselves or each other typically find their way. Its just a real shame that blown opportunities to raise kids for a couple of generations has such a high price tag. You can attack me all you want...... even when angrily arguing with people over this situation, the fact is, in terms of culture..im right and thats what really ticks people off when I post. I'm daring to shoot a hole in the armor of a bunch of spoiled suburban workout junkies....

YN, I was simply responding to Shan who was asking for censorship of this blog. You can attack me if it makes you feel better or you could stop reading this blog if it upsets you so much. I think its very important for the community to discuss this situation and other problems that adversely affect the place where we live. Maybe we can make changes by having open discussions. Cody Hall is not our only problem, we have many others but if maybe people reading this watch their kids a little more carefully going forward, we've made progress. If you are a supporter of Cody's, I am not here to judge you. I am only here to discuss some of the issues surrounding this problem which ultimately affects us all. Diana was a friend to many in this community, as well as a beloved wife and mother. She's gone now due to the thoughtless behavior of Cody Hall. Of course people are deeply emotional over this. If some are here working through their sadness, lets allow it so as a community we've come together. We may be of opposing thoughts, but at least the lines of communication are open. Rico, I also have witnessed very entitled behavior from many children in this community regardless of social or economic standing. I'm not from Pleasanton originally so I don't quite understand it, but have often been taken aback by what I've experienced over the years. I agree, we have to parent our children more tightly...there's obviously a problem.
A Reader August 16, 2013 at 03:30 PM
Some here would defend Cody as having made a "mistake". Bull. His bragging posts and his prior reckless behavior made this killing inevitable. The most telling reason to brand him as a sociopath is the complete lack of remorse as has been documented here and on other sites. Cody has stated that he is a victim, that Diana "should not have been there", that the car he passed "forced him to do that". A sociopath sees no wrong in any of his actions nor does he have any conscience. What more evidence do we need that what he has already provided to label him that? He is beyond redemption, he needs to be locked away from society for the rest of his miserable life. There are some people who simply cannot be changed, take a look at his dad and you will see that this entire family places no value on human life or the laws of society. Cody plays at sorrow with his tears in the courtroom. He is sorry only for HIMSELF, not for what he did, he is having to pay the price for his willful actions. As my late Mom used to say, "you want to cry, I'll give you something to cry about". Self pity is ugly, man up Cody. You are getting what you deserve. 15 to life.
Grant Halcomb Rummel August 16, 2013 at 05:32 PM
this little brat is surely going to make some friends in jail...that'll probably inspire a bit of remorse. throw away the key to this murderer.
Mitch rosenberg August 16, 2013 at 06:48 PM
Rico you are obviously the smartest person in the world and everyone else is stupid.
Rico August 16, 2013 at 06:51 PM
Never said that Mitch....but my observations certainly strike a nerve with you...guilty conscience I guess. like I said...attack if you want but you KNOW the culture here is fake flawed and another F I wont throw out here...
Mitch rosenberg August 16, 2013 at 07:00 PM
You saying that your right and everyone else is wrong is pretty arrogant of you. And maybe your old ass dosent remember what it's like to be 18 but people make stupid decisions. I agree that he should be charged with vehicular manslaughter but not murder. People change places change just because things are changing in your beloved little town dosent mean you need to get angry. Move somewhere else that makes you happy nobody's forcing you to stay here
Rico August 16, 2013 at 08:29 PM
Mitch you read things then put words into them. I never said everyone else is wrong. i said there is a large group "a significant minority"...heck I even said it was a MINORITY. that is causing a cultural problem in Pleasanton. If your going to go on a panic attack at someone at least be accurate. Your post probably wont last long because you cant keep yourself in check to not use profanity. I choose to stay and speak my mind and affect the place that I was born and raised in. Don't you DARE think for a moment you will intimidate me to move from here. Clearly its people that have your "if you dont like it, leave it" theory that are part of the issue that my post talked about... it must have cut a little too deep for you Mitchy...your cussing and not getting the facts straight now.... Murder is just fine with me. he earned it....
Rico August 16, 2013 at 08:30 PM
@ Mitch..follow up....clearly again I'm not alone..there have been several folks recommending my posts and posting in similar thought..... again..inaccurate....sad for you. Polish your BMW...it will make you feel righteous again
Mitch rosenberg August 16, 2013 at 10:06 PM
Why do you think I'm getting mad I'm not im laughing about how much you think your better than everyone else and you getting mad because you don't have as much money as everyone else your mad at this kid because you were clearly jellous of Aaron hall when you were in high school . Get over it
kax August 16, 2013 at 10:39 PM
how in the hell did this discussion get so full of hatred??? is it possible to disagree without killing each other??? i'm sitting here right now wondering what DD would make of all this. she was probably the most non-confrontational person i've ever met....and certainly one of the most peaceful......i know remembering that right now is helping me.....perhaps some of you could give it a try.....
L Leonard August 17, 2013 at 04:06 AM
Rico, I can appreciate your remarks, but I also want to tell you that not all Pleasanton kids are like this. I do understand why this reputation exists, but I have two teenagers (one at FHS and one that just graduated from FHS) myself and we've worked very hard to help them understand the concept of earning what you have with next to no handouts from us. My oldest had to save and buy his own first car and my youngest started babysitting at 13 because she will be doing the same. My oldest has had a job since the age of 16 and knows that we'll pay for college and dorm life as long as he has a part time job to cover his misc. expenses. My youngest will graduate in two years and it will be the same for her. I know it might seem that all parents here are like the Hall's and spoil their/our children rotten, but please know this is not the case. While my youngest does have some friends that live in multi million dollar homes with no understanding of the concept of budgeting or working for anything, she actually has more friends with parents like us who don't believe in buying our children anything and everything they desire. It is quite obvious by the grammar and the "texting" type of spelling in the writings on here that support Cody that they are likely his friends because no parent or educated adult I know would write as these posts are written. This is of great concern to me because I really hoped by choosing to raise my children in Pleasanton from K through 12th that they would be surrounded by responsible children from good families which is obviously not always the case given what other younger members of this community are posting on here. My only hope is that as they watch Cody fall hard that they'll grow up and realize that conducting themselves in this manner can literally take their entire lives away from them and that mom and dad can't buy their way out. His friends will move on with their lives and Cody will be forgotten and left to rot in prison. And I'm sure that even then, the only sorrow he'll feel is for himself.
L Leonard August 17, 2013 at 04:15 AM
A note to Diana's family and friends..... Ever since hearing of Diana's loss and how it happened, I have been especially mindful anytime I see a cyclist on the road. I've never been an irresponsible or reckless driver, but do know that I know I'm not the only one that is extremely cautious when sharing the road with cyclists and I do so thinking of your beloved family member and friend. When my teenagers are in the car with me and we see a cyclist, I also remind them of how vulnerable the cyclist is and remind them to make sure to give them plenty of room. We often talk about what happened to Diana when we talk about this. I know it can't bring her back, and nothing can make up for your loss, but I want you to know that many of us drive differently around cyclists and are teaching our children to do the same to make sure that this doesn't happen again even without the reckless driving Cody Hall displayed that day. God Bless you all.
kax August 17, 2013 at 12:16 PM
L. Leonard.....thank you so much for the kindness you send our way.....so much better than a lot of the hatred and anger we read here.....we are all learning some big lessons, these days...
Shan August 17, 2013 at 12:36 PM
Thank You L leonard! It is so refreshing to see someone step up for Pleasanton Parents and Our Children. Not everyone has the mentality of Cody Hall. As a matter of fact, I don't know any kids here that have a total disregard for human life when they get behind the wheel. One bad seed does Not define our children. I was raised in this Wonderful city since the early 70's. I left briefly, only to come back Home to Pleasanton to raise my own family ( I have 4 kids ) Not one of them is spoiled. They also Value others lives as well as their own. I LoVe Pleasanton and will not sit idle and read ridiculous stereotypical posts attacking US as a community. I can't imagine anyone on this board actually being a resident here and throwing up so much hatred. I certainly don't appreciate being judged. I LoVe Pleasanton ~ I LoVe Our Children ~ I LoVe our Neighbors. One bad seed does not define US.
JLE August 17, 2013 at 03:15 PM
Rico I'm wondering a few things ? How old you are, do you have kids of your own, what city are you from, and lastly what H.S. did you attend. I attended Amador for a year and a half went on to graduate Foothill in 85. I played sports and made friends from all over the bay area. I lost countless friends in all types of car accidents some driving the car some sat passenger and some through no fault of their own, still all were victims and tragedies. I have children of my own now a son 24 and a daughter 27. (oh and they were raised in Pleasanton) I have been here for 41yrs and all through these years I've seen parents who were very strict some who weren't so much some who were involved and some who weren't at all. The cities they resided in wasn't a factor. Every generation going back to my grandparents has seen its share of parents who don't have time for their kids makes no difference where they come from if it's because they are busy with work or whatever reason . Your frustration with Cody is warranted. Pleasanton is not responsible for this terrible tragedy nor are all "Pleasanton Parents" or our children. So if I were to answer my own questions I would have to say you are probably a bitter middle aged man who didn't attend school with no kids and definitely not a hometown guy. You seem to have some major hostility towards Pleasanton and the parents and children who live here. How can you honestly say this tragedy is the fault of Pleasanton, the parents or the children? Are you mental? My heart goes out to the family of the victim and the Hall family these lives are changed forever and they are all victims in a sense. A huge tragedy for all. But never fear Rico I'm sure justice will be served and you will happy to know it looks like this time it will be right here from good ole Pleasanton.
JLE August 18, 2013 at 01:17 AM
Oh and by the way Rico Aaron isn't from Pleasanton.
Mark August 18, 2013 at 11:57 AM
JLE, How are the Hall family victims? Of their own arrogance? Of their belief that actions have no consequences? Of having too much money and too little respect for the law/the other people who live in the area? For all those who want us feel sorry for Cody what kind of sentence should be imposed on someone drives 83 on an 40mph two lane road? Has also in the two plus years of legally driving managed to wreck not one, not two. but THREE cars (what kind of parents keep giving him a car after wrecking two?). Remember who the real victims are. The ones who forever lost a wife, mom, grandmother, sister. All because they were riding a bicycle in a bike lane on a June day. What kind of sentence do you hand out?
A Reader August 18, 2013 at 12:28 PM
What kind of sentence? 15 to life, preferably leaning toward life. This kid is past being reformed or remorseful. Ask any member of the real victim's family how much regret or compassion has been expressed directly, or indirectly, to them from the Hall's. Yeah, that would be exactly none.
Mark August 18, 2013 at 03:26 PM
JLE, What if Rico has an axe to grind against Aaron Hall? Does it make what Cody Hall did more forgiveable or even understandable? Does it make any sentence he posted less truthful? If you think Rico has an axe to grind avoid reading his comments it's that simple.
SuzySaver August 18, 2013 at 04:02 PM
It sickens me to hear the Hall family - especially Cody- have not shown remorse to the victim's family. That is just unthinkable. But that's what a sociopath does. Thinks only of himself. Tragic family.
