A student is in custody on suspicion of stabbing of a faculty member, the Los Angeles Police Department said. The department responded to a 9-1-1 call received at 4:35 p.m. Friday inside the Seeley G. Mudd Building at USC.

A memo from President C. L. Max Nikias has identified the victim as Bosco Tjan, a psychology professor. The Los Angeles Fire Department said he was dead when paramedics arrived at the scene.

The LAPD identified the student suspect as 28-year-old David Jonathan Brown on Saturday. He has been arrested for murder with a $2 million bail, and his case will reach the office of the district attorney in the coming week.

Brown was a doctoral student in the neuroscience program and worked as a teaching assistant in the biology department. He worked with Tjan in the professor's lab for visual research.

Speaking to gathered press Friday night, LAPD Detective Meghan Aguilar said Brown did not resist arrest and was transported to a nearby police station without incident.

Aguilar emphasized that the stabbing was not a random act, but instead targeted Tjan specifically. For that reason, "the safety of this campus is not in question," she said. It was not yet clear whether Brown had previously made threats to Tjan.

Investigators planned to interview witnesses and review video surveillance footage, if available.

Nikias said in the memo that counseling services are available to help students and university employees. Dean of Religious Life Varun Soni plans to lead a reflective prayer event on Monday.

Updated Dec. 5, 8:45 a.m. PT: This story was updated to reflect Brown's new bail amount of $2 million. Previously, the sheriff's department listed it at $1 million.
