A Buxton man who lives in a home where a day care center operated was charged Monday with possession of child pornography. Peter J. Blanchette, 27, was arrested on a charge of possession of sexually explicit material, said Stephen McCausland, spokesman for the Maine Department of Public Safety. Blanchette lives with his mother, Alma York, who operates the County Corner Kids Daycare in her home at 455 Long Plains Road in Buxton. McCausland said state police investigators have determined that York was unaware of her son’s activities and had no involvement with the child pornography that her son was allegedly viewing. State police contacted the Maine Department of Health and Human Services, which licenses County Corner Kids Daycare.
