“We do not know motive at this point for what occurred,” Radus said. “We do not believe there is a random stabber.”
Authorities described the suspect as an Asian man in his mid-20s with black hair wearing black pants and a black shirt. Police said they sent tracking dogs after him because he was last seen on foot and do not believe he is an active threat to the community.
Campus authorities were not aware of any threats against Chan, Radus said. The victim lived in Hacienda Heights, police said.
University officials increased security on campus and offered counseling and support services. Classes begin later this week at the nearly 40,000-student commuter school in Orange County, according to the university’s calendar.
“Our hearts and prayers go out to the family of the victim and all those affected by this tragic and senseless loss,” Fullerton President Framroze Virjee said in a statement. “The safety and support of our Titan family remains our top priority, now and in the hours and days to come.”
