OSWEGO COUNTY, N.Y. -- It's been 20 long years since family and friends have seen Heidi Allen.
Thursday the small community of New Haven came together, to remember the missing woman.
Police say she was kidnapped while working at a convenience store in the town.
Gary Thibodeau was convicted in connection to the case, but Heidi Allen has never been found.
People gathered outside the New Haven firehouse, holding a candlelight vigil to remember Heidi.
The family says for the last 20 years, the tight knit community has been supporting them.
Heidi's mother says life will never be the same after that tragic day in 1994.
Sue Allen, Heidi's mother said, "I think it's changed because I don't have Heidi, and 20 years later I still don't have Heidi. And I want that closure."
Lisa Buske, Heidi's sister said, "You know you see her friends get married, have kids. She didn't get married she didn't have kids. Our kids were going to grow up and we were going to continue sister day shopping on Thursday nights. It's kind of cool that April 3 is a Thursday, because that's sister day."
The Oswego County Sheriff's Department considers it an open and active case to this day.
