When family noticed McInnes had an injured hand, she told one story about how she cut herself slicing apples and another about how she fell on a rock.

Later that day, McInnes bought crayons and latex gloves at a dollar store. She anonymously called 911 to report suspicious activity, but gave no address before she hung up.

On the night of Sept. 23, Kaye’s roommates came home and discovered Kaye’s body on his bed, covered in blood. His left hand and ankles were bound to the bed frame with rope and there was a bandana around his neck.

As part of her plea, McInnes admitted that she tied Kaye up after convincing him it was for a sexual purpose. The autopsy showed she then stabbed him 40 times and cut him another 23 times.

The day after the murder, McInnes returned to the apartment and wrote “Murder #3 — This is not over pigs” in a deliberate attempt to mislead investigators.

McInnes “was very unemotional and she stayed very calm” when police notified her of her husband’s murder, Watson said.

Though McInnes deleted all information from her phone, investigators were able to trace the 911 call to her and discovered news articles about women who kill their male partners and dozens of incriminating Internet searches.

In previous weeks, McInnes’ online searches included:

Kaye was an apprentice mechanic who loved working on cars and trucks, said a former roommate shortly after the murder.

“He was a man who knew what he wanted out of life,” said Reino Mislenovich. “If I was having problems, I’d talk to him and he would do the same. He was the kind of guy who, if you treated him right, he’d treat you right.”

McInnes will be sentenced in 2016.
