Authorities on Saturday released the name of a USC student who had been arrested the night before on suspicion of stabbing one of the university's psychology professors.
Police detained 28-year-old Los Angeles resident David Johnathan Brown on Friday night after the attack on professor Bosco Tjan, co-director of the Dornsife Cognitive Neuroimaging Center, according to Los Angeles Police Department Officer Mike Lopez. Brown's bail has been set at $1 million.
Police did not immediately disclose information about Brown, or say whether they were aware of any motives that may have led to the incident.
Officers responded to the stabbing around 4:30 p.m. in the campus' Seeley G. Mudd building on McClintock Avenue. Tjan was pronounced dead at the scene, officials said.
The professor joined the faculty in 2001. According to a USC website, his laboratory studied the "human visual system to address basic and translational questions pertaining to vision loss, restoration and rehabilitation."
This isn't the first attack on a college professor in Los Angeles this year. On June 2, engineering professor William Klug was shot and killed in a murder-suicide by a former Ph.D. student.
In October, a jury found an 18-year-old woman guilty in the July 2014 beating death of a Chinese engineering graduate student. Xinran Ji was walking back home to his apartment after a study session around 1 a.m. when he was brutally attacked with a metal baseball bat and wrench.
In April 2012, two other engineering graduate students from China were killed less than two miles away from the USC campus. Ming Qu and Ying Wu were talking in a car outside Wu's residence after studying that night when a gunman approached the vehicle and shot both dead.
