WELD, Maine — Police say a report of a woman’s death in a Maine home led to the discovery of her 3-year-old son sleeping in a room with illegal drugs and used syringes.

The Franklin County Sheriff’s Office says it was notified of the unattended death of 29-year-old Elspeth Donnelly, at the home in Weld on Tuesday. The cause of her death is under investigation.

Her boyfriend, 35-year-old Ian Klanfer, who took her to the hospital, has been charged with endangering the welfare of a child. He was taken to the Franklin County Detention Facility. It wasn’t immediately known if he had a lawyer.

A couple visiting from Texas were found sleeping in another bedroom. They were not aware that Klanfer and another occupant had left during the night.
