Police believe a Windsor couple found shot to death in a car outside a drug store in Enfield died in a murder-suicide.
Two witnesses called 911 and said Milton shot Megan, then turned the gun on himself, police said.
The witnesses were not at the scene when officers arrived and police are looking to find them and get more information about what led up to the shooting.
Police told MassLive that Milton and Megan had driven separate cars and met in the parking lot. They are considering it a "case of domestic violence."
