A Michigan woman pleaded guilty Friday to the 2015 murders of her husband and their dog.

Yvonne Helen Cortis pleaded guilty to second-degree murder and killing/torturing an animal in the beating deaths of her husband Gregory Cortis and their 11-year-old yellow Labrador retriever. She admitted to beating them with a metal bar to put “them out of their misery,” according to a report by Daily Mail.

On November 30, 2015, police reportedly received a call from Cortis, who told them her husband and dog were “no longer suffering.”

When police arrived, they found Gregory Cortis moaning and suffering from a sliced ear and a gash on his head. He was rushed to the hospital, but died on December 12, 2015 from his injuries. An autopsy ruled his death a homicide, and determined that he died from blunt force trauma with complications.

The dog was also alive when police arrived but was not responsive. He died in January 2016 from his injuries.

Paul Walton, chief assistant in the Oakland County Prosecutor’s Office, said the prosecution was prepared to go to trial on December 7, but the defense wanted to enter a plea. After speaking with the police department and the victim’s family, the prosecution agreed to only charge Cortis with second-degree murder.

Cortis will be sentenced on January 3. She could be facing up to life in prison for the murder charge and four years and/or a $5,000 for the animal torture charge, the Detroit Free Press reports.

Milford Police Chief Thomas Lindberg said he has “complete confidence” in Walton for the decision to charge Cortis with second-degree murder.
