Correction: An earlier version of the story incorrectly spelled Tammy Mattison's name.

Peoria police have identified the mother killed while her 12-year-old daughter was home.

Tammy Mattison, 49, was shot in the head Friday at her apartment in the 8800 block of West Peoria Avenue. Her daughter and a neighbor called 911, and reported to police that the girl's father may have shot her, according to Officer Brandon Sheffert.

The father, 53, was later found with a gunshot wound to the head in a separate apartment he lived in at the same complex, Sheffert said in a news release. Police have not released his name. He was taken to the hospital with life-threatening injuries, but was still alive as of Saturday afternoon, Sheffert said. The child is with family, he said.

"We are doing everything we can to assist her while dealing with this horrific incident," Sheffert said in the release.

According to police reports, the couple were living in separate apartments "due to the couple's recent relationship issues."

The 12-year-old girl called 911 at about 3:45 p.m Friday after she found her mother shot inside their apartment, Peoria police said. According to police, a neighbor came to help the girl after hearing a loud bang.

Mattison was found bleeding heavily from the ear and, according to officials, a bullet casing was found near the body. Police said Mattison was unconscious and unable to speak. Officials took her to a hospital where she later died.

Peoria's SWAT team checked the man's apartment. Officers saw him on the floor and, after he failed to respond, they entered the apartment, Sheffert said. The man had a single gunshot wound to his head but was still breathing, Sheffert said. He was taken into custody and taken to a hospital, Sheffert said.

"Obviously it's a very tragic situation for everybody ... especially for this young girl," Sheffert said. "She ... saw her mother lying on the ground, bleeding. She needed help; she did the best she could, getting help on the way."

Police said there are no other suspects at this time and they believe the incident was isolated between the mother and father. But police ask anyone with additional information to contact Peoria Police Department.
