Heidi Allenâ??s sister will discuss the challenges and difficulties families face after a loved one goes missing or is kidnapped.

Lisa Buske will unveil the cover of her book "Whereâ??s Heidi? One sisterâ??s Journey" at 4:30pm on Friday afternoon in the Oswego County town of New Haven.

The event is scheduled to take place at the Heidi Allen Memorial Garden near the intersection of Route 104 and Route104b in the Oswego County town of New Haven.

Allen disappeared on Easter morning 1994. She was 18 at the time. Allen was working as a cashier at the D & W Convenience store when she disappeared. An Oswego County Sheriffâ??s deputy was flagged down by a customer who found the store empty at 7:50am.

The Oswego County Sheriffâ??s Office has said foul play was the cause of her disappearance. A massive search was conducted by police, the National Guard, troops from Fort Drum and hundreds of volunteers, but Allen was never found.

Brothers Richard and Gary Thibodeau were charged with Kidnapping in the 1st degree in connection with Allenâ??s disappearance. Gary Thibodeau was found guilty and sentenced to 25 years to life. Richard Thibodeau was found not guilty. Gary Thibodeau appealed his conviction in 1999 and 2007.

The Oswego County Sheriffâ??s and the FBI consider Allenâ??s disappearance to be an open case.

The website for the Oswego County Sheriffâ??s Department says Heidi Allenâ??s disappearance is considered an open case and deputies "continue to follow leads, hoping to find the remains of the missing woman."

The Valley News Online says that Oswego County Sheriff Reull Todd and Allenâ??s parents will be present at todayâ??s book cover unveiling.

The book is expected to be released in the spring.
