Fullerton Police said that a backpack, believed to have been left by the suspect, was located underneath Chan's vehicle. Inside the backpack investigators located an incendiary device along with numerous items "that were consistent with a kidnapping attempt or plot," including zip ties, wigs and other disguise materials as well as a knife, authorities said.

Police said that the backpack played a "significant" role in the investigation that led to Vo's arrest.

"We are confident that the backpack did belong to the suspect," Radus said during Thursday's press conference.

Police are still working to determine a motive for the killing.

Despite the arrest, police said they will continue to have a beefed-up presence on campus to reassure Cal State Fullerton educators, students and staffers.

Cal State Fullerton President Fram Virjee called the killing "an isolated incident," saying "we have no information there's any lingering danger to the health and safety of our campus."

"I come today with a heavy heart, with a heart full of emotion and love and caring, but also a deep sense of loss for our community," Virjee said. "Our hearts are with Steven Chan and his family."
