A manhunt is currently underway for Aaron Pennington, the husband of Breanne Pennington, who was found dead in their Gardner, Massachusetts home on Sunday. The Massachusetts State Police have released a photo of Pennington and are warning the public to consider him "armed and dangerous."

Four children, ranging in age from 2 to 9, alerted a neighbor to their mother's death, stating that their father was not home and that their mother was crying in her bedroom. Responding officers found Breanne Pennington with a gunshot wound to the face. Police have discovered three shell casings in the bedroom but have not yet located the weapon.

Court documents reveal that Breanne Pennington had been planning to move to Texas with the children to escape her husband's mental health issues. While it is known that she had a firearm in the house for protection, neither she nor Aaron Pennington had a license to carry a firearm in Massachusetts. Aaron Pennington is now facing charges of unlawful possession of a firearm.

The search for Aaron Pennington is centered around a heavily wooded campground in Gardner, a location used by the Boy Scouts and churches. Authorities are urging anyone who sees Pennington to call 911 and to not approach him.

Despite requests from residents, the city of Gardner has advised against holding vigils for Breanne Pennington at this time, as the focus needs to be on the ongoing investigation and search for the suspect.
