Wednesday marks two years since Aaron Pennington allegedly killed his wife inside the couple's Gardner, Massachusetts home, and police are continuing to search for information in the case as he remains at large.

Investigators say Pennington shot and killed Breanne Pennington on October 22, 2023 inside her home on Cherry Street in Gardner. Breanne was planning to leave for Texas with her four young children before she was killed as the couple was having marital problems, court documents later revealed.

Following the discovery of Breanne's body, police began a massive search of the surrounding area. The next night, Pennington's car was found in the woods.

The search continued for more than a week, but Pennington was never found.

Family believes he is still alive

Breanne's aunt Brenda Hull believes Aaron Pennington is still alive. 

"He blends in, I think that he's not very noticeable. I think that we certainly haven't done a very good job putting his face out there and I think that needs to change," Hull said in a phone interview with WBZ. 

He is 6'2" tall, 175 lbs. with a pronounced Adam's apple. Long limbs are among the descriptors of Aaron she wants known nationwide. 

"We don't want to tell Breezy's life story. We don't want to talk about the children. We want to talk about Aaron. We want to put his picture out there," Hull explained. 

"The most important piece that we consider the children and so it's very important that they have that closure and that they know what their father is or what's become of him," Hull added. 

Investigation ongoing

Worcester County District Attorney Joseph Early Jr. says his office remains committed to bringing justice to Breanne Pennington and her family. 

"The investigation into her murder and the whereabouts of her husband, Aaron Pennington, remains active and ongoing," Early wrote in a statement, while adding law enforcement may conduct additional searches in the Gardner area. 

Anyone with information on the case is asked to contact the Worcester District Attorney's office at (508) 832-9124.
