A possible murder unfolded in Ensley Township, Michigan, in May 2015 and an unexpected witness was present at the scene - Bud, an African grey parrot.
Mr Martin Duram, 45, was fatally shot at his home on 128th Street and his wife Glenna, who suffered a gunshot wound to her head, survived.
She was found next to his body in what police initially thought was a double homicide.
However, in an unusual turn of events, Mrs Duram is now a suspect in a murder-suicide, according to Michigan State Police reports which were acquired under the Freedom of Information Act by 24 Hour News 8.
Bud, who was the victim's pet, has reportedly been mimicking his owner's voice and words, and was caught on video saying the phrase, "Don't f***ing shoot!"
The relatives of Mr Duram feel that Bud should be a key witness for this suspected murder-suicide by Mrs Duram and that the video of Bud imitating his owner's voice is crucial evidence in this case.
According to The Washington Post, Mr Duram's mother Lillian told Wood TV: "That bird picks up everything and anything, and it's got the filthiest mouth around."
Mr Duram's father Charles said of Bud: "I personally think he was there, and he remembers it and he was saying it."
In the video, Bud appeared to be mimicking both husband and wife and changing voices - as if there was an argument.
Ms Christina Keller, Mr Duram's ex-wife who now owns the African grey parrot, told the TV station that Bud replayed recognisable voices of a man and a woman who seemed to be in a serious argument.
She added: "When it happens, my house turns cold."
According to The Independent, the owner of Casa La Parrot in Grand Rapids agreed, saying it was not strange for African grey parrots to imitate voices of males and females.
However, lawyers have expressed their concerns about Bud's "evidence".
Newaygo County Prosecutor Robert Springstead told The Associated Press on Monday (June 6): "I'm not aware of any legal precedent for that."
Mrs Duram had denied allegations that she left three suicide notes for relatives before the shooting occurred, police records revealed. She said she could not recall writing any note.
"I know for a fact I didn't kill my husband," police quoted her as saying, according to The Washington Post.
