Former Westlake High and NFL Star Guilty of Drunk-Driving Murder

Former Westlake Village High School football star and NFL player will be sent to prison after pleading guilty to killing a California Lutheran University professor in a 2020 drunk-driving accident.


On November 15, 2022, 41-year-old Mike Seidman pleaded guilty to felony gross-vehicular manslaughter while intoxicated on October 16, 2020. Seidman caused a head-on collision that killed 88-year-old Fred Rosenberg.

Rosenberg worked as a CLU professor for a significant number of years. He was still teaching classes and volunteering with the Los Angeles County Sheriff’s Department before the crash.

Seidman was driving northbound in a silver pickup truck on Erbes Road approaching Hauser Circle. He lost control of his vehicle and veered into the path of Rosenberg. They both collided head-on.

According to the DA’s office, Seidman had alcohol and marijuana in his system during the crash.


The District Attorney’s office agreed to a four-year sentence in return for Seidman’s plea. Seidman was facing 10 years in prison. Shortly after the crash, he was free on $250,000 bail. He is due to be sentenced on January 24.

On the night of the crash, Seidman was driving with a suspended license. On August 4, 2019, he was arrested on suspicion of DUI after crashing his car near Avenida de Los Arboles and Westlake Boulevard and then leaving the scene.

The four-year sentence agreement covers both the 2019 and 2020 cases. When asked about why it took over two years for the case to be resolved, the DA said that “A lot of cases were backlogged.”
