NEW HAVEN, N.Y. (WRGB) — Wednesday marked 30 years since 18-year-old Heidi Marie Allen disappeared from New Haven, New York.
On Easter Sunday on April 3, 1994, Allen was working alone as a cashier at the D&W Convenience Store on the intersection of State Route 104 and 104B in New Haven. She opened the store at about 5:45 a.m. Just over two hours later, the store was reported to be vacant at approximately 7:55 a.m.
She rang up her last transaction at 7:42 a.m. and has not been seen since.
Allen's family held a vigil at the New Haven Fire Department, where they held the first one for Allen 30 years ago.
Decades later, the investigation into her disappearance continues, and support continues to pour in for Allen's family.
"We're never alone when you have people showing their support and love. Sometimes it's a hug, a smile or a handshake, but it doesn't have to be big stuff," said Lisa Buske, Allen's sister. "Tonight is big stuff to me."
At the time of her disappearance, she was 5 feet 11 inches, 145 pounds with long curly light brown hair and blue eyes. She was last seen wearing a gray sweatshirt with a plaid "SU" logo on the front and white sneakers. She wore glasses or contact lenses and had pierced ears.
In 1995, Gary Thibodeau was convicted of kidnapping Allen. He maintained his innocence for nearly 25 years until he died in prison in August 2018.
Richard Thibodeau, the brother of Gary Thibodeau, was accused of the same crime but was found not guilty in a separate trial. He passed away on Jan. 2.
In 2019, on the 25th year mark since Allen's disappearance, her sister Lisa Buske maintained her belief that her sister was kidnapped and murdered.
WRGB aired the "Heidi Allen Files" special in 2019, detailing a year-long investigation that revealed a hidden document in the case.
The investigation continues and anyone with information into Allen's disappearance is asked to contact the Oswego County Sheriff's Office at (315) 349-3411.
