A graduate student has been charged with a single count of murder in the fatal stabbing of a beloved University of Southern California professor, the Los Angeles County District Attorney’s Office said Tuesday.
David Jonathan Brown, 28, also faces a special allegation that he personally used a deadly and dangerous weapon in the crime, according to a DA’s news release.
He is scheduled to be arraigned sometime Tuesday.
Brown is accused of fatally stabbing 50-year-old Siaufung “Bosco” Tjan inside the professor’s office in the Seeley G. Mudd building on USC’s campus late Friday afternoon, according to police.
A motive for the case was not immediately known, but the Los Angeles Police Department — which is investigating — believes the killing was “targeted,” the L.A. Times reported. Brown, a student in the professor’s introductory lab course, was at the scene of the fatal stabbing when police arrived.
Tjan, the co-director of the Dornsife Cognitive Neuroimaging Center, had joined the USC faculty in 2001, according to his profile on the university’s website.
Hundreds of people gathered on campus Monday to remember the slain professor at a memorial.
“Tragically, Bosco died doing what he loved, doing what he believed in — serving his students and building up a new generation of scholars,” USC President C.L. Max Nikias said. “His achievements are real, his influence enduring.”
Brown faces a maximum sentence of 26 years to life in prison if convicted as charged, according to the DA’s office.
