A suspect has been arrested in a rash of serial arson cases in Mission Viejo over the last week, authorities said.

The suspect, identified as Jack Frye, 19 of Lake Forest, is being held on suspicion of six counts of arson and one count of attempted arson, including two trash can fires at Mission Viejo High School that cost the school an estimated $3,000 in damage.

A cooperative investigation between the Orange County Fire Authority and the Orange County Sheriff’s Department brought the suspect in with the aid of surveillance footage from Mission Viejo High that proved instrumental in identifying the suspect, said Captain Alan Wilkes of the OCFA.

Frye was arrested while allegedly trying to start a seventh fire back at Mission Viejo High, Wilkes said. He is expected to appear in court in the coming days.
