Mervyn Groton, known as Sunny, worked the Naval Education Training Center in Newport, Rhode Island.

He was a machinist main instructor, responsible for teaching future sailors how to operate the steam turbines that propelled and powered ships.

Sunny spent the weekdays at the base in Newport.

Every Friday, he drove to his home in Belfast, Maine, to spend the weekend with his family.

On Friday, December 16th, Sunny drove home like he did every weekend.

But this was not like other weekends.

He pulled into the driveway, got out of his truck, and was shot three times.

He didn't make it into his house ever again.

He died that night on the way to the hospital.

From A&E, this is cold case files.

Detective Richard Richel from the main state police began his investigation by talking with the victim's family, including studies Winogne Norma and their children.

This is Detective Richel.

Nobody saw anything. I wish they had. It would have certainly helped the investigation if we could have got some type of physical description of the perpetrator.

A canine officer was brought in to aid the human officers in their search for evidence.

An area search dog is able to pick up the scent of a human in an open area.

Depending on the weather, they can detect a scent anywhere from 100 to 300 feet away.

I found two casings on the ground near a couple of woodp piles out back where a canine handler had picked up the scent.

The casings were from a common hunting rifle, the 30-30.

The woodpile where the casings were found were close to the tree line at the edge of the property,

so the police dog was sent to investigate.

They found and tracked the scent of the killer a quarter of a mile through the woods until they came to a road.

The canine handler said that the dog lost the scent, which would indicate that the perpetrator, in all likelihood, got into a vehicle and drove off.
