PLEASANTON, Calif. (AP) — Police and prosecutors say an 18-year-old alleged who killed a bicycle with his car has had a vehicular manslaughter charge upgraded to murder in part because he boasted about speeding on Twitter.
The San Francisco Chronicle and Oakland Tribune report that Cody Hall of Pleasanton is being held without bail on Thursday, a day after he was charged with the murder of 58-year-old Diana Hersevoort.
Authorities say Hall hit Hersevoort and her husband on June 9 along a busy boulevard in Dublin on June 9.
Prosecutors say an analysis of Hall’s driving record along with Twitter posts where he discussed how fast he liked to drive convinced them to change the charge to murder.
Neither the newspapers nor The Associated Press could reach an attorney for Hall for comment.
