Prosecutors have filed new murder charges against a Plymouthman more than three years after a shooting critically injured his girlfriend and ultimately led to her death.

Austin Robert Le Claire, 30, is now charged with second-degree murder with intent in connection with the Nov. 25, 2022 shooting inside a garage at a Plymouth residence.

The upgraded charge was filed after Daisy Colonnese, 26, died in August 2025 from complications tied to a gunshot wound to her head.

According to the criminal complaint, Plymouth police were called to the home shortly after 7:19 p.m. on Nov. 25, 2022. The 911 call came from Le Claire, who told dispatchers he had been talking on the phone with Colonnese when he heard a gunshot. He said she was at their shared residence on 40th Place in Plymouth and claimed he was on his way home from work.

When officers arrived, they entered the garage and found Colonnese lying face down near a large pool of blood with an apparent gunshot wound to the head and was unresponsive. A neighbor flagged officers down and said Le Claire was still on the phone. That neighbor also told police he frequently heard arguments between the couple and said Le Claire had previously threatened Colonnese and others with a gun.
