Sheriff’s deputies shot and killed a Hartford man after receiving a report of domestic assault Saturday evening.

The Oxford and Androscoggin County sheriff’s offices responded to 299 Tucker Road in Hartford at approximately 4:45 p.m. on Saturday after an 80-year-old man reported that his stepson, Eric Newell, 51, assaulted him.

According to a release from the Oxford County Sheriff’s Office, deputies attempted to “deescalate the situation” but were unsuccessful.

Newell exited the residence and advanced toward deputies while armed with a knife, the sheriff’s office said.

Oxford deputies Reece Rodrique and Derek MacDonald both shot Newell after he did not comply with their demands, the release said. Newell died from his injuries.

Both deputies were placed on administrative leave, as is standard protocol when deadly force is used. The Office of the Maine Attorney General will be investigating the use of deadly force.
