Authorities said Thursday they are searching for 53-year-old Christopher Wheeler and asking for the public's help in locating him.
Wheeler stepped down as headmaster of Tower Hill School last week after the attorney general's office searched his home and school office as part of a child abuse investigation.
Authorities say an examination of computers that were seized during the searches recovered multiple images of child pornography.
Detectives with the state Child Predator Task Force secured an arrest warrant for Wheeler on Wednesday, charging him with 25 counts of dealing in child pornography.
