A Petaluma man accused of driving drunk and causing a deadly crash on Lakeville Highway last month has been officially arrested for his role in the incident, police announced Tuesday.

Jesse Cockrill, 25, was arrested Monday by Petaluma police on suspicion of gross vehicular manslaughter and felony drunk driving causing major injury or death. Police said they intercepted Cockrill at Santa Rosa Memorial Hospital and booked him in the county jail. Bail was set at $485,000.

Cockrill had spent several weeks recuperating there following the horrific crash on Lakeville Highway near Pineview Avenue in which Betty Osotonu, a 65-year-old Vallejo resident, was killed. A passenger in Osotonu’s vehicle, an 8-year-old girl, sustained minor injuries.

Police said the crash occurred Saturday, June 7 at a little after 10 p.m. They said Cockrill, whose blood alcohol content was later measured at .16, swerved his Lincoln LS into the eastbound lane and hit Osotonu’s Toyota Camry head-on.

Cockrill was already on probation from a previous arrest and was not allowed to drink alcohol under the terms of his probation, according to police. The crash was the first traffic-related fatality this year in Petaluma.
