Her death devastated loved ones and forever changed the lives of her children.
The Days Leading Up to the Murder
According to police records, the Penningtons had been experiencing marital difficulties in the weeks leading up to Breanne's death.
On October 21, 2023, Gardner Police responded to the family's Cherry Street home after Breanne reported concerns regarding Aaron's anticipated return to the residence.
Officers discussed available options with Breanne, including the possibility of seeking a restraining order.
Less than twenty-four hours later, tragedy struck.
October 22nd, 2023
On Sunday morning, authorities responded to 42 Cherry Street in Gardner after receiving reports of an emergency.
Inside the home, Breanne Pennington was discovered deceased from an apparent gunshot wound.
Four young children were present in the home during the incident.
Investigators quickly focused their attention on Aaron Pennington, who had fled the area before police arrived.
The Search for Aaron Pennington
Following the homicide, law enforcement agencies from across Massachusetts launched an extensive manhunt.
Search efforts included:
- Gardner Police Department
- Massachusetts State Police
- Worcester County District Attorney's Office
- Air and ground search teams
- K-9 units
- State Police Special Emergency Response Team (SERT)
Investigators later located Aaron Pennington's abandoned BMW near Camp Collier and wooded areas off Kelton Street in Gardner.
Despite intensive searches involving helicopters, drones, tracking dogs, and hundreds of officers, no trace of Aaron Pennington was found.
Wanted for Murder
On October 25, 2023, prosecutors announced that a murder warrant had been issued for Aaron Pennington.
Authorities have stated that he should be considered armed and dangerous.
Investigators believe he may have received assistance after fleeing Gardner, though no public evidence has been released confirming his whereabouts.

Without Aaron's capture, many of those questions remain unresolved.
