FBI investigators say they may have found who killed 55 year old Glenn Cawley in March of last year.

 

36 year old Michael Southerland pleaded guilty Monday to illegally possessing guns that may be connected to the unsolved murder.  Michael was involved romantically with Cawley's wife at the time of his death.

 

The victim's widow, Lillian Cawley, who was living in California at the time, hadn't heard from her husband in over four hours so she asked the police to check up on him.  He was found shot to death in his home on March 12, 2015.

 

FBI investigators say this could break this cold case wide open.
