Heidi was not scheduled to work that day.
The young woman was filling in for a co-worker who had taken off to give her children their Easter baskets--as it was Easter Sunday.
Heidi opened the store at 5:45 am, but was found to be missing at 7:50 am.
Her jacket, purse, and car keys were found inside the store, and her vehicle was left undisturbed in the parking lot.
There was cash in the register and on the counter, but no sign of the clerk.
The store did not have working video cameras.
Two brothers were eventually arrested and charged with her kidnapping. Richard Thibodeau was found guilty and is serving 25 years to life in prison. His brother was found not-guilty after a separate jury trial.
But Heidi Allen has not been seen since that morning at work.
Almost twenty years missing.
She has written four books (including one on her missing sister and how it changed Lisa's life).
She is also a blogger.
To publicize the upcoming yet tragic 20th anniversary, she has written a series of heartfelt posts on her missing sibling.
The pain, the grief, and the struggle to understand "why?"
I hope Lisa's writings help other families who struggle with lost loved ones.
Whether it is a first anniversary, a twentieth, or more.
