Update: Sunday Night Crash Was Attempted Suicide

Authorities believe the driver who hit a utility box and pole on Camino Tassajara Sunday evening was attempting to commit suicide.

Leif Bostrom, a 30-year-old Danville resident, crashed at about 5 p.m. and suffered major injuries, including a fractured hip and sternum, after being thrown from his silver Audi A4 sedan, according to California Highway Patrol Officer Tyler Hahn.

Bostrom was reported missing by his wife earlier that day and witnesses reported that Bostrom refused their aid following the collision, saying that "he wanted to die," according to Hahn. 

Witnesses also reported that Bostrom drove straight into the utility box "without any brake lights," said Hahn, who added that there were notes left at his home indicating he was intending to commit suicide.

The silver Audi A4 sedan was heading eastbound on Camino Tassajara near Blackhawk Drive.  After the crash, Hahn said investigators found the speedometer locked at 71 mph.

The crash occured just east of town in an unincorporated area of Contra Costa County.

Authorities have not yet determined if alcohol was involved, Hahn said.  Bostrom's current condition is unknown, though his injuries were not life threatening.

A trust fund has been set-up to help the Bostrom family with medical bills.
