LISBON — State police say they may have found the skeletal remains of a woman who was brutally murdered last year in the town of Lisbon.

Christiana Fesmire of Lewiston has been missing since July 2011. A jury convicted the 22-year-old woman’s killer — Buddy Robinson of Lewiston — last month even though police had been unable to recover the victim’s body.

Prosecutors presented evidence during a November trial that convinced a jury the 31-year-old Robinson beat and drowned Fesmire in her bathroom before dumping her body in a swampy area in the woods.

Court documents portray Fesmire as part of an online prostitution ring led by Robinson’s sister, who told police that her brother confessed to the killing.

Steve McCausland, a spokesman for the Maine Department of Public Safety, said the remains were discovered around 1 p.m. Tuesday.

He said Lewiston and Lisbon police were involved in the recovery of the remains, which were found along a trail about 200 feet off a road near the intersection of Wagg and Ferry roads.

The remains will be taken to the State Medical Examiner’s Office, which must determine whether the remains are those belonging to Fesmire.
