WATERVILLE – A Waterville man who worked with Boy Scouts was charged Wednesday with possessing child pornography on a laptop computer, police said.

Charles H. Tisdale, 24, was arrested after the computer was analyzed by the Maine State Police Computer Crimes Unit. He was charged with possession of sexually explicit material, a felony.

Waterville police said Tisdale has been affiliated with the Boy Scouts for the last six years and has regular contact with children through his job with Sequel Care of Maine and Employment Specialists of Maine.

Police said there is no evidence that Tisdale has had any criminal contact with children.

Tisdale is married and has a daughter, both of whom live with him, police said.

Since October, he has served as volunteer chairman of the Special Needs Scouting Committee for the Downeast District of the Pine Tree Council Boy Scouts of America, said District Executive Adam Corzatt.

In light of the criminal charge, Tisdale’s registration with the Scouts has been revoked, Corzatt said.

Tisdale worked primarily with adult volunteers in Sagadahoc, Lincoln and Knox counties, Corzatt said. He trained unit leaders in adapting activities to accommodate special-needs scouts.
