A foul-mouthed parrot may provide key evidence in the murder trial of a Michigan woman accused of killing her husband more than a year ago.

Glenna Duram, 48, was charged Thursday with first-degree murder in the death of Martin Duram, who was found shot five times in May 2015 at their home in Sand Lake. Glenna was found lying next to Martin with a gunshot wound to her head.

Martin’s family claims the couple’s pet parrot, Bud, likely witnessed the murder after the bird was heard saying “Don’t f------ shoot” in a video taken shortly after Duram’s death, WOOD reported.

The prosecutor told WOOD he hasn’t ruled out using the winged witness on the stand as evidence.

“That bird picks up everything and anything, and it’s got the filthiest mouth around,” Duram’s mom, Lillian Duram, told the station.

According to police, Glenna maintains her innocence saying “I know for a fact I didn’t kill my husband.”

But investigators suspect a murder-suicide plot gone awry. Glenna allegedly wrote three suicide notes and the couple had financial problems, according to police records. One of the alleged suicide notes, left for one of her children, apologized for being “a disappointment to you these last 12 yrs or so.” The note asks the reader to “Please forgive me.”

"No matter what happens I lose, I lost a son and I’m gonna lose a daughter-in-law," Martin’s father Charles Duram told Fox 17. "But when I wake up in the morning my wife ain’t crying and asking for justice, I can live with that."
