SAN BERNARDINO, Calif.  – A Rialto man was sentenced Friday to 7 years in state prison for driving in a grossly negligent manner resulting in the death of 27-year-old Tan Phung in Oct. 2016.

Last month, Alex Reider, 27, pleaded guilty to one felony count of Gross Vehicular Manslaughter, one felony count of Hit-and-Run Causing Death, and one felony count of Insurance Fraud. The maximum penalty for Gross Vehicular Manslaughter under the California Penal Code is 6 years.

According to Deputy District Attorney Tom Colclough, who prosecuted the case, on Oct. 29, 2016, Tan Phung’s car became disabled on the 210 Freeway near Waterman Avenue in the city of San Bernardino. While inspecting his car, Mr. Phung was struck by another car driven by Reider who fled the scene without stopping to render aid. Mr. Phung died while being treated at Loma Linda University Medical Center. 

Reider made a report to the San Bernardino County Sheriff’s Department that his Infinity was stolen on Oct. 28, 2016 while he and the car were at Daniel Cordona’s home in Rancho Cucamonga. The California Highway Patrol later recovered the Infinity in an unincorporated area of San Bernardino.

“The defendant filed a theft claim with his insurance provider to repair front end damage to the Infinity that he claimed was caused during the theft,” Colclough said. “DNA testing of blood discovered on the Infinity revealed Alex Reider’s blood on the driver’s door and Mr. Phung’s blood on the front fender.”

Daniel Cordona, 27, of Rancho Cucamonga, was convicted of perjury, insurance fraud, and being an accessory after the fact. In Oct. 2017, he was sentenced to three years of felony probation that included 270 days in county jail. 

The San Bernardino County District Attorney’s Automobile Insurance Fraud Unit and the California Highway Patrol jointly investigated this case.
