SAN JOSE — A San Jose man wanted on suspicion of setting his parents’ house on fire last week was arrested Tuesday in Salt Lake City after authorities there said he crashed a stolen car into a tour bus while high on heroin then fought with police.

Casey Keil, 29, was being sought by the San Jose Police Department stemming from a June 5 altercation where he allegedly assaulted his stepfather, followed by him dumping and igniting gasoline at his parents’ Terrace Drive home a block north of San Jose High School.

Firefighters quickly extinguished the blaze, which caused minor damage to the home. San Jose police searched for Keil but couldn’t find him.

Then Tuesday, witnesses told Salt Lake City police a man later identified as Keil was driving a sedan that collided with a tour bus parked in the Utah city’s downtown at about 7:20 a.m. The bus was unoccupied at the time, and when officers arrived, Keil was passed out behind the wheel, Detective Dennis McGowan said.

As the officers try to pull him out of the wreck, Keil woke up and started fighting with them, and tried to start the car to flee, McGowan said. One of the officers used a stun gun to subdue him. Besides cuts and scrapes, no other injuries were reported.

While searching and examining the car Keil was driving, police learned the vehicle was reported stolen in San Jose, and they found a syringe containing heroin on the passenger seat, McGowan said. They also linked Keil to a felony affidavit from the San Jose assault and arson case.

Keil was booked into Salt Lake County jail on suspicion of offenses including hit-and-run, resisting arrest, possessing a stolen vehicle and possessing a controlled substance and related paraphernalia.

Keil has also been identified as a “sexual predator” by the state of Illinois, stemming from a 2004 incident in Kendall County in which he sexually abused an unidentified teenage victim. Keil was 20 at the time of the conviction.

An extradition plan to send Keil to California was not immediately detailed Wednesday.
