Norfolk District Attorney Michael W. Morrissey on Tuesday issued a new appeal for the public’s help in solving the disappearance and possible murder of a 23-year-old Quincy woman who vanished two years ago.
In a statement, Morrissey said State Police found “substantial blood evidence” in the apartment of Evelin Valibayova after she disappeared on July 17, 2011.
“By working with friends, we recovered a personal item of Evelin’s and were able to find and test a sample of DNA on one item,” Morrissey said. “That DNA profile matched the blood found in the apartment. . . . We believe very strongly that there is foul play involved, and that she may in fact have been murdered.”
The district attorney said authorities need help in identifying a man who used Valibayova’s Charlie Card at the Ashmont MBTA stop in Dorchester days after she disappeared.
Officials do not believe the man, who was captured on surveillance footage wearing multi-colored pants, had anything to do with Valibayova’s disappearance, but they would like to know how he obtained her card.
Some of her possessions were dumped in the Dorchester/Mattapan area, according to the statement.
Morrissey added that Valibayova was planning to sublet an apartment in the Allston-Brighton section of the city in August 2011, and that authorities are trying to determine the exact address.
“Someone knows where that is, because they arranged the sublet or had planned to room with her,” he said. “They may not believe that what they know of her is important, but we need to talk to them.”
David Traub, a spokesman for Morrissey, said Tuesday that authorities have identified a person of interest in the case, but he would not elaborate. Traub said he could not comment on whether anyone had a motive to harm Valibayova.
Working telephone numbers for her relatives could not be located on Tuesday.
Last summer, Morrissey announced that several billboards asking for information about Valibayova’s disappearance were going up in the Boston area.
“That push resulted in zero calls to police,” the statement said.
Quincy Police Chief Paul Keenan referred questions on the case to Morrissey’s office.
Valibayova, a native of Azerbaijan, was last seen arriving at the North Quincy Red Line station on July 16, 2011, after her shift at Area Four, a Cambridge restaurant. Authorities believe she made it back to her apartment in North Quincy before she disappeared.
No one has seen or heard from her since, according to the statement.
“If someone reading this has information on where she was going to sublet the apartment in the Allston-Brighton area or knows the identity of the man in the MBTA photo, if you thought someone else will step up and contact us, they haven’t,” Morrissey said. “And we need you.”
