Closing arguments were delivered Tuesday in the Los Angeles Superior Court in the trial of Alejandra Guerrero, the youngest of four suspects accused of killing a USC graduate student in July 2014.
Guerrero and three fellow suspects were teenagers when they allegedly approached 24-year-old engineering student Xinran Ji and attempted to rob him.
Ji, an international student from China, was walking home from a late-night study session at the time and did not understand what the suspects were asking. When he responded in Chinese, the suspects said they attacked Ji and violently beat him using a baseball bat and a wrench, according to their testimonies. Ji struggled to walk back to his apartment, where his bloody body was later discovered.
Guerrero was 16 years old at the time of the crime but is being tried as an adult. According to her testimony, she originally claimed a more backseat role in the incident as a sort of lookout for the group for police or witnesses. She later clarified that she had struck Ji with a wrench three times.
Guerrero is being charged with murder with a special circumstance allegation that Ji was murdered during an attempted robbery.
The judge will deliver final instructions Wednesday morning and jury deliberations will begin shortly after.
