PORTLAND (AP) – Officials say photos on the Internet helped trigger an investigation into an alleged underage drinking party in Portland that followed Deering High School’s state baseball championship.

Three assistant coaches were dismissed as a result of the June incident.

Deering Principal Ken Kunin said photos of the party posted on popular social networking sites – and reported by parents and students to the school – helped confirm that the three coaches were at the party.

Portland police are continuing their investigation, which could lead to alcohol-related charges.
