A woman was arrested after allegedly shooting her husband to death in Union City, authorities said Monday.

Officers were investigating the homicide just after 8 a.m. in the area of Feldspar Court after reports of a shooting inside a home, according to the Union City Police Department.

A man was found with gunshot wounds and pronounced dead at the scene.

His cohabitant, a woman believed to be his wife, was arrested for his death.

Dispatchers received a 911 call about 10:15 p.m. Sunday from the wife that “she just shot her husband,” according to the police dispatch.

The gun was reportedly still in the room with the husband.

“She’s saying she doesn’t know what happened,” the dispatcher said.

“She says he’s been treating her really bad all week. She’s not sure where she shot him. She’s saying she shot him 16 to 18 times,” the dispatcher added.

The dispatcher then told the woman to come outside of the house where police were waiting.

Both the victim and suspect were not identified pending notification of next of kin.

Authorities advised residents to avoid the Feldspar Court area as detectives investigate the scene.

No other information on the slaying was immediately available.
