STOCKTON — The former volunteer Franklin High School wrestling coach accused of having a romantic relationship with a teen girl who had been reported missing made his first court appearance Tuesday afternoon in San Joaquin County Superior Court.

The San Joaquin County Sheriff’s Office arrested Philip Maglaya Jr., 25, in connection with the weeklong disappearance of a 16-year-old girl, who is back at home with her family. The San Joaquin County District Attorney’s Office is charging Maglaya with several sex-related felonies.

Superior Court Judge Ron Northup on Tuesday read aloud the charges filed against Maglaya, which include child abduction and child abuse or neglect. Maglaya was appointed a public defender and remained in custody. He is being held on $1.375 million bail.

Maglaya is due back in court at 8:30 a.m. Sept. 11 for further arraignment.

Authorities initially reported that a Franklin High School student was reported missing on Aug. 22 and it was believed she was with Maglaya, and that the two were in a romantic relationship. Maglaya had worked as a volunteer wrestling coach last year at Franklin High.

The pair was found on Aug. 30 after an anonymous tip led deputies to a home on East Mendocino Avenue in central Stockton. Authorities said the girl was found physically unharmed and to be in “good condition.” She was returned to her family.

Maglaya was subsequently arrested and booked into the San Joaquin County Jail.

The District Attorney’s Office previously said Maglaya used his position of trust to pursue an inappropriate relationship with the girl and the charges reflect the breach of trust. It also is alleged that he removed the teen from her parents against their wishes, concealed her whereabouts for more than a week and engaged in acts with her to which she cannot legally consent.
