People v Alexander David Yohn

On June 30th, 2016, a jury found defendant Alexander David Yohn guilty of second degree murder and gross vehicular manslaughter while intoxicated.

On the evening of March 24, 2014, Defendant Yohn drove from his home in Emeryville to a bar in Fremont to go on an OkCupid date. While on the date, the defendant consumed twelve shots of whiskey. Defendant Yohn was told by his date that he was too drunk to drive and his date called the defendant’s roommate to come pick him up. Despite his roommate telling the defendant he would come and pick him up, Defendant Yohn chose to drive. Defendant Yohn drove to Taco Bell and ordered food. The Taco Bell employee saw how intoxicated the defendant was and called 911.

Just as police arrived at the Taco Bell, Defendant Yohn sped off down Fremont Boulevard. Defendant Yohn drove at 80 mph -- twice the speed limit -- down Fremont Boulevard and ran the red light at Thorton Boulevard. Defendant Yohn continued speeding and ran the red light at Decoto Road.

The victim, Andrew Silva, was driving through this intersection at the time and Defendant Yohn plowed into Mr Silva's motorbike. Mr Silva was home from a recent overseas deployment as a Marine and was driving his motorcycle along on Decoto Road to his in-laws house in Fremont.

Mr Silva was killed from the blunt force trauma caused by Defendant Yohn's vehicle hitting him. Defendant Yohn left the scene of the crime and continued down Fremont Boulevard and crashed into a pole. Defendant Yohn fled from the vehicle into a nearby field, and was eventually detained by police.

Defendant Yohn's blood alcohol level approximately one hour after the collision was .23%. The defendant additionally had Suboxone, an opiate used to help with his heroin addiction, in his system. Defendant Yohn had also been previously convicted of driving under the influence in 2010, where he had a blood alcohol level of .24% and had collided with a parked car.

The case was prosecuted by DDA Ashley Dodson with the assistance of DA Inspectors Robert Davila and Gus Galindo and Victim-Witness advocates Jenifer Mello and Rhoden Briones.
