A woman in Otisfield reportedly led police to a double homicide in Zephyrhills, Fla., on Tuesday when she called to report she was unable to reach her sister living in that city.

At about 10:45 a.m., Zephyrhills police found the bodies of Irene Martin and a man she had been living with in a mobile home at 38059 Lawanda Loop, police said. Both bodies were found inside the doublewide trailer, police said.

At about 3:45 p.m., a Maine State Police trooper and Oxford County Sheriff’s deputy went to Otisfield to notify Martin’s sister about the death, Maine Department of Public Safety spokesman Steve McCausland said. The sister’s name and address were not released.

Zephyrhills police said a family member from Maine had called them Tuesday to report a lack of contact with Martin and asked them to check on her. Martin was said to be in her late 40s or early 50s, although her exact age was not available.

By late Tuesday night, police were still working to confirm the identity of the man whose body was found with Martin’s.

The cause of death was not released by late Tuesday night. However, a Zephyrhills police sergeant said the nature of the deaths led them to conclude almost immediately that the killings were intentional.

By late Tuesday night, police remained at the scene of the slayings. Investigators said Martin’s vehicle was missing from the residence and police around Florida were on the lookout for it.

Zephyrhills police put out a bulletin for police to be on the lookout for a sedan with handicap, Florida plates bearing the registration number 61149.

No arrests had been made in connection with the slayings by 10 p.m.

It was unknown if Martin lived in Florida all year, or spent part of her time in Otisfield. Several officials in Otisfield said Tuesday night they were unaware of anyone by that name living in town.

Zephyrhills is a city in west central Florida with a population of about 11,000. A Tampa Tribune reporter covering the killings described the Lawanda Loop neighborhood as a lower-to middle-class area comprised of mostly mobile homes.

Neighbors said they were familiar with Martin’s name but knew little about her. Several told the Tribune reporter that Martin was known to keep her lawn neat and trim.

No one answered a call at the home Tuesday night.
