Aaron Pennington, 33, of Gardner, Massachusetts, was last seen on October 22, 2023, after his wife, Breanne Pennington, was found dead from a gunshot wound in the couple’s home. Their four young children ran to a neighbor’s house for help after finding their mother unresponsive. Security footage showed Aaron leaving the residence in a white BMW sedan at about 8:50 a.m. that morning.

Two days later his vehicle was found abandoned by a hunter near a wooded area. Police and K-9 teams carried out extensive searches, but Aaron has not been located. Authorities have issued a warrant for his arrest, consider him armed and dangerous, and say Breanne had been planning to leave the relationship, a detail investigators are treating as relevant to the incident.

Anyone who saw Aaron, the white BMW, or who has information about his whereabouts in the Gardner area or beyond is urged to contact law enforcement immediately.
