A woman has been sentenced to life in prison for the beating death of a University of Southern California graduate student from China, and a co-defendant was given a term of 15 years to life.
Twenty-year-old Alejandra Guerrero was sentenced Friday on a first-degree murder conviction in the 2014 attack on engineering student Xinran Ji. Her prison term is without possibility of parole.
Authorities say Guerrero got out of a car to beat Ji with a wrench, while 23-year-old co-defendant Jonathan Del Carmen remained in the car. Del Carmen pleaded guilty to second-degree murder.
Deputy District Attorney John McKinney says after the attack Ji staggered to his off-campus apartment where he died.
A third co-defendant is already serving life without parole and a fourth is awaiting trial.
