Cody Hall To Serve 9 Years, Takes Plea Deal in Fatal Bike Collision

The teenaged driver facing a murder charge and felony reckless driving following a fatal bicycle collision last summer pleaded guilty today to vehicular manslaughter with a Great Bodily Injury enhancement as part of a plea agreement, according to officials at the Alameda County District Attorney's Office.

Pleasanton resident Cody Matthew Hall, 19, took the plea agreement during today's preliminary hearing at the Gale-Schenone Hall of Justice. Hall was charged with second degree murder, along with felony reckless driving in the June 9 collision that killed 58-year-old Dublin resident Diana Hersevoort. 

"Hall will serve a total of nine years; six for vehicular manslaughter and three years for GBI clause," Alameda County District Attorney's office spokesperson Stephanie Chan said. "This is also a strike offense."

In a previous Patch article, criminal defense attorney Mary Ann Bird says a guilty conviction for Hall could have put the teen in prison until he was in his thirties. If Hall had been convicted on the murder charge, Bird said Hall could have been sentenced up to 15 years to life in prison.

The Hall case drew national attention because his social media posts, along with his driving record, were likely going to be part of the foundation for the murder case against him.

In November of 2013, Hall was denied bail by Judge Jacob Blea after he entered a plea of 'not guilty' for all charges.

Hall has been at the Santa Rita Jail on a "no bail status" since he was taken into custody on Aug. 14 while appearing in court after prosecutors raised the vehicular manslaughter charge against Hall to murder.  Read the full story here.

According to documents submitted by police to the court, 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 on June 9. 

Hall will be back in court for sentencing on May 30.
