The recently unsealed arrest warrant is shedding new light on the investigation into a physician's assistant from Redding who was charged with his wife's murder.

Court documents show that on the night of April 6, Richard Commaille, 70, called 911 to report his wife, Nanci, had committed suicide in their home on Topledge Road.

Redding police say things at the scene didn't add up, so the investigation was turned over to Connecticut State Police. They arrested Commaille for murder earlier this month.

Commaille's warrant shows he told police his wife had been drinking excessively lately and spoke about killing herself. He also said he'd called 911 right away.

However, police found evidence his wife had been dead longer than he led them to believe and that the chair she was found in had been moved.

Investigators say she was shot in the head, but the gun was discovered to the left of her despite the victim being right-handed. They say the weapon had no fingerprints on it.

Police also found no blood on the victim's hands.

The report says they did discover blood spatter on a coat owned by Commaille and he tested positive for gunshot residue on both hands.

Commaille has a hearing in Danbury Superior Court set for June 30.

Redding's police chief says his officers had never been called to the home before the night of this incident.

Commaille's attorney Edward Gavin issued a statement to News 12:
