After Pennington’s vehicle was discovered on Monday, a Code Red warning was issued for area residents to remain in their homes for several hours.

Officials said the warning was issued only out of “an abundance of caution,” but added in an update Tuesday that they were moving back into the area near Camp Collier, a community forest for Boy Scouts.

Pennington allegedly shot his wife in their home around 9 a.m. Sunday, sending the couple’s four children β€” ages two, five, seven and nine β€” running to a neighbor’s house.

An officer on scene reported that the children ran to their neighbor because they were “scared because they couldn’t find their father and their mother was crying in her bedroom.”

When police entered the house, they found Breanne in an upstairs bedroom with a gunshot wound to the face, and Aaron’s car was gone from the driveway.

The complaint alleges that Pennington possesses an illegally possessed firearm without a permit to carry it, and although three shell casings were found in the bedroom, no firearms were found in the home.

Breanne was also known to have a gun in her home for protection, police said.

Surveillance footage showed the 33-year-old fleeing in a white BMW sedan at 8:50 a.m. on Sunday.

As police hunt for Pennington for a third day, Breanne’s heartbroken family shared their shock at the loss of the “loving, caring, compassionate” mother of four.

‘We are all in shock about this. We are all in shock. We had no idea something like this would ever happen,” said Brooke Pertile, Breanne’s sister Boston25.

‘He better turn himself in. He needs to stand up for what he did and turn himself in. And don’t be a coward. He must turn himself in. He has to do it for the children.’

Pertile said her sister lived for their children and was a “very loving, caring, compassionate woman” who “always saw the best in everything and in people.”

β€œShe absolutely lit up the room like no other, every room she walked into,” she added.

A criminal complaint revealed that the Penningtons’ marriage was problematic because Breanne planned to take their children to Texas and away from Aaron.

The complaint also alleges that Aaron suffered from mental illness and had threatened to kill himself.

‘From the outside he was a very nice person. But he struggles with a number of mental health issues. It just got worse,” said Breanne’s sister, who said she spoke to her three days before the shooting.

The couple’s children who fled for help are now reportedly in state care.

Gardner Mayor Michael Nicholson said that while the city has received numerous requests to hold a vigil for Breanne, he asked for a postponement “due to the fact that the investigation is still ongoing and because the suspect remains at large.”
