PARIS – A crowd of onlookers was kept behind a police line in the Oxford County Superior Court parking lot as Duane Waterman, charged with killing two men in West Paris, was led into the courthouse Tuesday.

One onlooker shouted at Waterman, calling him a “murderer” and a “menace to society.”

Waterman, 31, of Sumner did not enter a plea on Tuesday. A grand jury will decide later this month whether to officially charge him.

He was arrested Monday and charged with murder in connection with the shooting deaths of Timothy Mayberry, 50, of West Paris and Todd Smith, 43, of Paris. Both men were found dead of multiple gunshot wounds on July 26 at Mayberry’s residence on Tuelltown Road.

Relatives of the victims were in court Tuesday to see the man charged in the killings.

Katie Tripp of Oxford, whose husband is Smith’s cousin, described Smith as “happy-go-lucky” and “outgoing .”

“I think everyone’s just angry and wants to know why this is happening,” she said.

An arrest report provided by the Oxford County Jail states that the shootings occurred between 9:30 and 10:45 p.m. on June 25. Mayberry’s body was spotted by a motorist near a stone wall outside his house; Smith’s body was found inside. Police searched Waterman’s house for three days last week. He was arrested without incident Monday afternoon while fishing with his children on Brettuns Pond beside Route 4 in Livermore.

Superior Court Justice Roland Cole ordered Waterman held without bail until Sept. 3, when a bail hearing will be held. Cole said a bail hearing may be held earlier if one is requested.

He also ordered a 35-page police affidavit, which likely includes details of the search of Waterman’s house and what police found there, to be impounded until after the bail hearing.

Lt. Brian McDonough of the Maine State Police said the investigation was ongoing and that evidence was being analyzed at the state crime lab. “There’s a lot in the investigation and it’s very early into it,” he said.
