David Jonathan Brown, 28, has been charged with one count of murder in the stabbing death of USC professor Bosco Tjan, the District Attorney's office said in a release on Tuesday. The charge is supplemented with a special allegation that Brown used a knife, which in the court of law is regarded as "deadly and dangerous" weapon that may be "used in such a way that it is capable of causing and likely to cause death or great bodily injury."

Tjan, 53, was fatally stabbed inside USC's Seeley G. Mudd building on Friday afternoon. Police received a call at around 4:30 p.m. about a victim with multiple stab wounds. Tjan was pronounced dead at the scene, according to ABC News. Brown was detained at the vicinity of the incident.

Tjan had taught at the university since 2001, and was considered to be an expert in perception, vision and vision cognition. According to The Mercury News, Tjan served as a mentor to Brown, a doctoral student studying brain and cognitive science. Brown had also been working in a lab that was being run by Tjan. The USC Department of Public Safety said in a statement that the attack is believed to have been the "result of a personal dispute."

A memorial for Tjan was held at the Tommy Trojan statue on campus on Monday:
