Authorities launched a manhunt for a volunteer high school wrestling coach on Saturday who they believe is traveling with a missing teenage girl after the two were discovered to be in a “romantic relationship.”

Phillip Maglaya, a volunteer wresting coach at Stockton Unified’s Franklin High School, is believed to be traveling in a 1994 green Toyota extra cab truck with the 16-year-old girl, who was not identified. The truck has the license plate number 8G91493.

“On Wednesday, we took a missing persons report on a 16-year-old girl who we learned was in a romantic relationship with a wrestling coach at Franklin High School in Stockton,” San Joaquin County Sheriff’s Office said in a Facebook post on Saturday.
