Police on Tuesday hunted a black-clad attacker who fatally stabbed a retired administrator at California State University, Fullerton, in a campus parking lot. A 911 call sent officers to the lot Monday morning where they found Steven Shek Keung Chan inside his silver Infiniti.

He was bleeding from his head and had been stabbed many times, police said. Efforts to help him failed and the 57-year-old Hacienda Heights man died at the scene, police said.

A backpack believed to belong to the attacker was found under the car. It contained a knife-like weapon, items that could be used in a kidnapping and an incendiary device, Fullerton police Lt. Jon Radus said.

"It was basically like a bottle with flammable liquid and a potential igniter" but it had not been set off, Radus said.

The 911 caller described the attacker they saw run away as a man in his 20s with black hair, wearing black pants and a black shirt, Radus said. Officers using dogs searched for the man but couldn't find him. Police "will be working around the clock to identify the suspect involved," the department said in a tweet.

The attacker targeted Chan specifically, although investigators were still trying to determine the motive, Radus said. 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 Fram Virjee said in a statement.

Virjee said he did not know Chan personally "but over the past few hours, in providing a shoulder to lean on for those who were close to him, it is clear that he was beloved for his commitment to and passion for both Cal State Fullerton and our Titan Family."
