A Southern California socialite was found guilty Friday of murder and other charges in the hit-and-run deaths of two young brothers in a crosswalk more than three years ago.

Authorities said Rebecca Grossman, wife of a prominent Los Angeles burn doctor, fatally struck Mark Iskander, 11, and brother Jacob, 8, while speeding behind a car driven by then-lover Scott Erickson, a former Los Angeles Dodgers pitcher.

The jury found Grossman guilty on all counts: Two felony counts each of second-degree murder and gross vehicular manslaughter, and one felony count of hit-and-run driving resulting in death. She faces 34 years to life in prison.
