LOS ANGELES -- A jury found an 18-year-old woman guilty of first-degree murder Thursday in the 2014 beating death of a USC graduate student from China.
Alejandra Guerrero was also found guilty of second-degree robbery, attempted second-degree robbery and assault with a deadly weapon. She is one of four defendants accused of murdering Xinran Ji, 24.
Two years ago, Ji was walking home when authorities said video captured Guerrero and her co-defendants - Andrew Garcia, Jonathan DelCarmen and Albert Ochoa - stopping Ji on the street to rob him. They were armed with a metal bat and a wrench.
Security cameras from the electric engineering student's apartment building captured him as he returned home bloodied after the attack. He was later found dead inside the apartment, according to police and USC officials.
Guerrero's co-defendants' trials are scheduled to start in November.
