Prosecutors say Sina Khankhanian was despondent because he'd lost his job and drove his car into Emily Shane in Malibu in April 2010. The 13-year-old girl died at the scene.
Khankhanian's first trial ended in a mistrial in January. The girl's parents are relieved.
"The jury finally saw the truth and got justice for Emily," said Michael Shane, the girl's father. "And it won't bring her back, but at least we can close this chapter and move on."
Khankhanian faces up to 16 years to life in prison. He'll be sentenced June 15.
