WEST PARIS – Police concluded searches of two homes Thursday in their investigation into the shooting deaths of two men last weekend, but have not made an arrest in the case.

Spokesman Stephen McCausland of the Maine Department of Public Safety said Friday that interviews will continue, and some people may be interviewed again as more information comes forward. Interviews begin with family members, then extend to relatives, friends, and anyone the murder victims may have had contact with, he explained.

“Certainly we try to retrace their footsteps,” he said.

The body of Timothy Mayberry, 50, was discovered Saturday evening outside his residence at 89 Tuelltown Road. The body of Todd Smith, 43, a friend of Mayberry’s, was found inside the house.

The State Medical Examiner’s Office has determined that both men died of multiple gunshot wounds. Their deaths are Maine’s 21st and 22nd homicides this year.

Last year there were 21.

On Monday, police continued searching Mayberry’s home and served a search warrant at 30 Front St. in Sumner, the home of Duane and Naomi Waterman. Duane was released after being questioned by police, and a 1993 Jeep Cherokee registered to the Watermans was removed from the scene.

“He is one of dozens of people we have talked to in connection with this homicide investigation,” McCausland said.

He declined to comment on how much evidence was seized by police but said experts at the state’s crime labs are looking it over.

“In this case, we’ve been very open as to what we’ve searched,” McCausland said.

On Thursday, Naomi Waterman was sentenced in the Oxford County Superior Court to serve 90 days of a two-year sentence after pleading no contest to thefts from Wal-Mart in Oxford. Waterman’s attorney, Sarah Glynn, said Waterman had been incarcerated for about three weeks prior to the sentencing.

Also on Thursday, Chief Robert Stewart of the Sumner Fire Department told the town’s Board of Selectmen that state police suggested that he recommend the condemnation of the house at 30 Front St.

Stewart said he was asked by police to assist in the search of the residence using a thermal imaging camera near chimneys and the attic, but found nothing.

Stewart said the residence should be condemned and removed for health and safety reasons.
