PORTLAND — Family members are planning a memorial service for Margarita “Rita” Fisenko Scott even as police continue to try to find out where she was in the final days of her life.

Scott, 29, was found dead Thursday in a car outside Motel 6 on Riverside Street.

Police are processing the car at the regional forensics laboratory at the Portland police station as well as interviewing friends and family and following up on leads that have come in from the public, said Lt. Scott Pelletier.

“We’ve been receiving tips. We are following them all up,” he said. “We haven’t ruled anything out.”

Police plan to release more details about the case today in an effort to generate more leads as they work to track Scott’s killer.

Scott’s family said she hadn’t been in touch with them since before Christmas, and her parents filed a missing person’s report with police, said her cousin Alla Sherstyukov.

Sherstyukov said the family was told Scott was found in the back seat of the car, which was registered to both her and her husband and which she had taken after they broke up. They think she might have been dead for some time, because she did not call her grandmother on the older woman’s birthday, which was Jan. 15; and the following day, Wednesday, it snowed. The car was discovered Thursday covered with snow, she said.

Scott came to the United States as a girl from Kazahkstan, part of a large extended family that has emigrated here from the former Soviet republic on the southern border of west-central Russia.

Scott married her partner of several years, Cary Scott, in the summer, Sherstyukov said, and they split up in November.

“She said she needed to temporarily leave him,” Sherstyukov said. She didn’t know why they separated, but said they remained close and Cary Scott is devastated by her death.

The family plans a memorial service at the First Russian Baptist Church in Gorham. The service will be held at 5 p.m. Friday and all are welcome, Sherstyukov said.

Police say they have encountered a language barrier in interviewing some of Scott’s family members, who speak Russian, and they still have not spoken to all of them, even though detectives worked throughout the weekend, Pelletier said. Her husband, extended family members and others they have interviewed have been cooperative, he said.

Police are trying to reach friends and former employers, anyone who might have seen her in the days before her death.

At the request of police, the state medical examiner has not released the cause of death other than to say it was a homicide.

Police have canvassed businesses in the area where Scott’s body was found, trying to find security video that might provide clues, Pelletier said.

Police ask that anyone with information call 874-8604 or go to the police website, www.portland-police.com, to submit an anonymous tip.
