The suspect was identified as Chuyen Vo, 51, by police officials at a press conference on Aug. 22.
Fullerton Police Chief Robert Dunn said that the suspect was arrested at his house in Orange County around 10 p.m. on Aug. 21 after an investigation.
Police reached a sketch and video footage the day prior and asked for the public’s help in identifying the man.
Steven Shek Keung Chan, 57, of Hacienda Heights was found inside a silver Infiniti. He had been stabbed many times, police said.
Officials said that Vo was a co-worker of Chan but police did not specify how they knew each other. “Beyond them being co-workers, we cannot comment specifically on their relationship,” Dunn said.
“Members of our department and the CSUF department have worked around the clock since the investigation began,” Dunn added.
He didn’t indicate how exactly the suspect was located.
Cal State Fullerton President Framroze Virjee said at the press conference that he had “a heavy heart” after the death of Chan.
“We as a Titan family have suffered a devastating family that has hit close to home. Our hearts are with Steven Chan and his family,” he said, before thanking police officers for working hard on the investigation.

From 2009 to 2017, Chan was the university’s director of budget and finance and student services for university extended education, the university said.
He returned to campus as a special consultant in early 2019 “to provide his sage guidance and wisdom,” university President Framrose Virjee said in a statement.
A witness who called 911 at 8:27 a.m. said the attacker ran away, Fullerton police Lt. Jon Radus said. He was described as being in his 20s with black hair, wearing black pants and a black shirt.
A backpack found underneath the car contained a knife-like weapon, items that could be used in a kidnapping, and a bottle filled with a flammable liquid that was capable of being ignited by hand, Radus said.
No order was given to shelter in place after the attack because the man was believed to have left the campus, but police presence was boosted.
The attack came as campus police were filming active-shooter scenarios in Pollack Library and other campus locations as part of emergency preparation. The filming was canceled after the attack.
The nearly 40,000-student commuter school in the middle of its host city in Orange County has the largest enrollment in the 23-campus California State University system. It is well known in the sports world for producing nationally ranked baseball teams and major leaguers including Justin Turner of the Los Angeles Dodgers and Khris Davis of the Oakland Athletics.
The academic year started Monday, Aug. 19 but there were no students on campus, the university said. Weekend classes begin Saturday and weekday courses next Monday.
In 1976, a custodian with a history of mental illness opened fire with a rifle in the school library, killing seven people and wounding two others. Edward Allaway was initially convicted of murder but then found not guilty by reason of insanity and sentenced to a mental hospital.
