Evelin Valibayova, a 23-year-old woman from Azerbaijan, disappeared on July 17, 2011, in North Quincy, Massachusetts. Evelin was last seen leaving her job at a Cambridge restaurant just before midnight, and security footage later captured her at the North Quincy MBTA station around 12:27 a.m., just 200 yards from her apartment. She had plans to talk to her mother in Azerbaijan via Skype and had arranged to meet her boyfriend the next day, but she never made contact.

Her apartment on Hodges Avenue showed signs of foul play, including significant bloodstains in the bedroom and missing personal items such as her laptop and phones, though her passport and immigration papers were left behind. Several weeks later, her blood-soaked carpet was discovered, leading investigators to believe she had been murdered. Police quickly identified John Castonguay, a handyman with a history of violent crime, as a suspect. Castonguay had access to her apartment and was in the building the day she vanished. Despite being named a suspect, he has not been charged in connection with her disappearance.

Authorities believe foul play is involved, but Evelin's body has never been found, and the case remains unsolved.
