The following day, the California Highway Patrol identified the driver of the Chevrolet Tahoe, which crashed into an irrigation ditch, as 47-year-old Brian Boguhn.
The official cause of the crash is under investigation by the CHP, while a spokesman for the San Joaquin County Sheriff’s Department said the office is conducting an independent investigation into the official cause of death.
According to sheriff’s spokesman Les Garcia, investigators found a note and superficial lacerations on both of the victim’s arms.
“It appears it was an apparent suicide attempt,” Garcia said. “There is no evidence of foul play. It is not being investigated as a homicide.”
A close friend of the family on Friday strongly disputed the sheriff’s speculation about Boguhn’s final minutes.
The initial CHP crash report from officer Ed Epps, released on Friday, stated that Boguhn was driving north on Tracy Boulevard just south of Grimes Road at about 2 p.m. May 3 when his SUV went off the road. The vehicle rolled once and landed upside down in an irrigation ditch on the west side of the road.
Tracy firefighters arriving at the scene jumped into the water and used the Jaws of Life to cut Boguhn out of the wreckage. He was taken by ambulance to San Joaquin County Hospital in French Camp, CHP officers confirmed, where he died several hours later.
According to the report released Friday, alcohol was a contributing factor in the crash.
CHP spokesman Adam Shelton said Thursday that Epps’ determination was based on the discovery of empty and full bottles of beer scattered about the scene, which Epps believes came from the victim’s vehicle.
Garcia said it would be four to six weeks before an official toxicology report would be filed by the coroner’s office, but a family friend said that a blood panel taken at the hospital May 3 showed no signs of intoxication.
Friends of Boguhn said he is survived by a wife and five children, ranging in age from 2 to 13. He worked as an IT manager for Live OPS in Cupertino, according to his obituary.
