WALNUT CREEK -- With one woman dead and a second fighting for her life late Monday after Saturday's violent crash on North Main Street, details emerged about the suspect's history, which includes two arrests for driving under the influence.
Walnut Creek resident Hossein Tabrizi, who was driving a pickup that plowed into a family of four on a North Main Street sidewalk, has twice been arrested for DUI and once for being drunk in public, according to the Department of Motor Vehicles and the Ventura County District Attorney's Office.
Tabrizi, 53, was arrested for both DUIs in 2005, records show. One of the cases was dropped for reasons not clear Monday. In the other, he was convicted and sentenced to five days
On Sept. 9, 2005, Tabrizi was arrested for public intoxication, for which he served two days in jail, Gibbons said. And in 2007, Tabrizi was convicted of petty theft for a crime committed at a Ventura County JC Penney store.
Police in Walnut Creek have not said whether drugs or alcohol were a factor in Saturday's crash, but are investigating the possibility. Tabrizi was arrested on suspicion of vehicle manslaughter and could be arraigned Tuesday or Wednesday.
Lt. Lanny Edwards said it could take investigators
"We are not overlooking anything in this case," he said Monday afternoon.
Authorities said Tabrizi was driving south on North Main Street near the Marriott Hotel about 6:15 p.m. Saturday when his pickup veered onto the sidewalk and slammed into four people -- a grisly crash witnessed by hotel employees and guests.
The collision killed Sherry Hicks, a 52-year-old math teacher from Santa Barbara, and sent her daughter-in-law to the hospital. Hicks' son and husband were not injured.
According to friends, Hicks was in Walnut Creek visiting her son and his wife, who moved here for work after graduating college.
Hicks' son Casey Hahn is married to Sheng Hahn, who was listed in critical condition Monday afternoon at John Muir Medical Center in Walnut Creek.
Casey and Sheng Hahn graduated from the University of California, Santa Barbara this past spring. At UCSB, the pair were bright actuarial science and the "heart and soul" of the Actuary Club, said Michael Ludkovski, co-director of actuarial studies.
Casey Hahn works for the Towers Watson consulting firm in San Francisco, Ludkovski said. Sheng Hahn began working as an intern with the actuary consulting firm Milliman in San Francisco a month ago.
"This is horrible, our hearts go out to her. We are hoping and praying for a full recovery," said Jim Loughman, spokesman for Milliman.
Tabrizi was in custody as of Monday morning in lieu of $50,000 bail, according to the Contra Costa County Sheriff's Office.
