Warning: This video may be disturbing to some viewers. A man who plowed through Venice Beach's crowded boardwalk Saturday evening, killing one and injuring 11 more, has been arrested and identified as 38-year-old Nathan Louis Campbell. The woman killed was identified as Alice Gruppioni, 32, of Italy. Gruppioni had been married just three days when she was struck and killed while walking the boardwalk with her newlywed husband- the pair were on their honeymoon. "There were people flying, laying on the ground, tents flying everywhere. If he wanted to kill people, he came on a perfect time, 5 p.m. on a Saturday in the summer in Venice Beach," a witness told CNN. Campbell turned himself in a few hours after the crash, and was arrested and booked on murder charges in connection with the incident.
