VAN NUYS (CBSLA.com) — A scam artist was sentenced Wednesday to a decade in prison for staging traffic collisions and demanding thousands of dollars in compensation from elderly victims.

David Stevens, 42, pleaded not guilty in 2014 to multiple charges stemming from incidents between Oct. 25, 2013 and Jan. 6, 2014 in the San Fernando Valley.

“My blood pressure went up. I don’t trust people now like I did,” 93-year-old victim Lee Gormley said.

Police say Stevens targeted Gormley and at least nine other elderly people at upscale grocery stores, followed them as they drove away, honked to get their attention and then accused them of hitting his car.
