Ohio woman kills 3 family members before turning gun on herself as deputies were serving eviction notice, police say

An Ohio woman killed her son, husband and father last month before turning the gun on herself while deputies were trying to serve an eviction notice, police said.

The Clermont County Sheriff's office believes Theresa Cain, 46, killed Ethan Cain, 13; Steven Cain, 50; and William Felton, 74.

Samantha Cain, 20, who police identified as Cain's daughter, was also critically injured in the shooting, police said.

Deputies were responding to the Clermont County home on Feb. 27 at 9:41 a.m. to serve the "writ of possession," an order announcing that the bank had taken possession of the home, Chief Deputy Chris Stratton told NBC News.

"While approaching the residence, multiple gunshots were heard from inside of the residence," a statement from the Clermont County Sheriff's office said. "Repeated attempts to contact the occupants were unsuccessful and the Sheriff's Special Response Team responded to make entry."

Authorities found five gunshot victims inside the home, four of whom were dead and one alive. The living victim, later identified as Cain's daughter Samantha, was taken to an area hospital where she is "in critical but stable condition," police said.

Basing their assumption on preliminary autopsy reports, officers believe that Cain killed her three family members and injured her daughter before dying of a self-inflicted gunshot wound all while deputies were on the scene to serve the eviction notice.

Cain's motive for the shooting remains unclear.

"Samantha's progression could provide vital information into this horrific incident which could assist detectives with answers as to motive, which remains under investigation," the sheriff's office said.
