LOS ANGELES—An 18-year-old woman was convicted Thursday in the beating death of a Chinese graduate student at the University of Southern California as he walked home after a late-night study session.
Alejandra Guerrero was the first of four people to be tried in the slaying of 24-year-old Xinran Ji during a robbery attempt in 2014. Guerrero was found guilty of first-degree murder and other charges.
