Police are investigating a domestic violence incident during which a grandmother is suspected of shooting and killing her granddaughter, authorities said Sunday.

Just after 4 p.m. Dec. 15, Buckeye police responded to a call about a shooting at a home near 254^th Avenue and Carson Drive.

Officers issued commands for those inside the home to come outside, and a woman believed to be in her 50s left the house and was detained without incident, police said.

Officers went inside the home and found a woman in her early 30s with a gunshot wound. She was unresponsive. The woman was taken from the home and lifesaving measures were attempted. They were not successful.

Officers then found another woman, who is in her 70s, inside the home with a handgun nearby. She was detained without incident, according to a release from the Buckeye Police Department.

“Information gathered on scene suggests this was a domestic violence incident involving a grandmother, mother and granddaughter and that the grandmother shot the granddaughter,” the release stated.
