Murder Suspect Aaron Pennington Still at Large; Released Note Hints at Premeditation

Search intensifies for Aaron Pennington, suspect in wife's murder; Pennington's military background and history of mental health issues under investigation as critical factors in his evasion.

Aaron Pennington, a murder suspect in his wife's death, remains at large after fleeing his family home on October 15 and has been charged with murder; authorities described him as 'armed and dangerous'.
A chilling note was discovered on Pennington's phone reading 'put a hole in her head', written the night before his wife, Breanne Pennington, was found shot dead; this evidence hints at premeditation of her killing.
Adding complexity to the ongoing search, recent reports suggest Pennington possesses military training and has a history of mental health issues, with previous suicide attempts mentioned in court documents.
Authorities have intensified their search and are examining over 400 acres of woodlands near Aaron Pennington's abandoned car, as well as looking into his background in the U.S. Air Force.
Breanne Pennington was reportedly planning to move to Texas with their four children to escape the troubled marriage; the children are currently in the care of Massachusetts Department of Children and Families.
