She had been gone for 4 months. When she finally reached a pay phone, she was shaking so badly she could barely speak.
The call she made that night in March 1987 ended one of the most horrifying cases in American criminal history and saved 3 lives.
This is the story of Josefina Rivera, the woman who brought Gary Heidnik down.
It begins in November 1986, on a street in North Philadelphia. Gary Heidnik, 43 years old, is driving through the neighborhood when he picks up Josefina Rivera, 25. He lures her to his house with the promise of money. Once inside, he chokes her unconscious. When she wakes up, she is chained in the basement.
She does not know it yet, but she will be there for 4 months. And she will not be alone.
Gary Heidnik is not what he appears to be. On the surface, he is a man of modest means who has managed to turn a $1,500 investment in stocks into a portfolio worth over $500,000. He has founded a church — The United Church of the Ministers of God — in his North Philadelphia home, and holds regular services in his living room for a congregation that includes mentally disabled members. He is, by all appearances, a man of God.
In his basement, he is something else entirely.
Over the following weeks and months, he abducts 5 more women, all Black, all from the same North Philadelphia neighborhood. Sandra Lindsay, 24, is taken on December 3. Lisa Thomas, 19, is taken on December 23 after Heidnik drugs her wine. Deborah Dudley, 23, is taken on January 2, 1987. Jacqueline Askins, 18, is taken on January 18. Agnes Adams, 24, is taken on March 23 — just one day before everything unravels.
He keeps all 6 women captive in his basement in a pit he has dug himself, chaining them, depriving them of food, and subjecting them to repeated physical and psychological abuse. He feeds them dog food. He forces them into complete darkness for days at a time. 2 of the women — Sandra Lindsay and Deborah Dudley — do not survive.
Josefina Rivera survives by doing something extraordinarily difficult: she makes Heidnik trust her. Over 4 months, she convinces him she is on his side. She gains his confidence. And on March 24, 1987, she persuades him to let her out of the house, supposedly to visit her family. He agrees, and parks nearby to wait for her return.
Rivera does not go to her family. She goes to a pay phone at 6th and Girard Avenue. She calls 911. And then she goes to her boyfriend's apartment to wait, her clothes filthy, her wrists and ankles scarred with the marks of months in chains.
When police arrive, they are not entirely sure what to make of her. Rivera forces them to look at her body — the bruises, the raw scars, the evidence of what she has endured. Officers go to Heidnik's home at 3520 North Marshall Street.
What they find inside stops them cold.
In the kitchen, on the stove, a pot. Inside it, Sandra Lindsay's dismembered remains. In the freezer, more of her remains, stored in bags. In the basement, the pit — boarded over, barely ventilated. Inside it, 3 women: Lisa Thomas, Jacqueline Askins, and Agnes Adams, alive, chained in the dark.
Heidnik is arrested without incident. He is still parked nearby, waiting for Rivera to return.
In 1988, a Philadelphia jury convicts Gary Heidnik on 2 counts of first-degree murder and multiple counts of kidnapping, r**e, and torture. He is sentenced to death. His defense team argues he is mentally ill and that Rivera was the true instigator — a claim the jury rejects entirely. On July 6, 1999, Gary Heidnik is executed by lethal injection at a Pennsylvania state prison. He is the last person executed in Pennsylvania as of this writing.
His crimes are so disturbing, so methodical, so utterly hidden behind the facade of a church and a quiet neighborhood, that Thomas Harris later cites him as one of the inspirations for the character Buffalo Bill in The Silence of the Lambs. The basement pit where Heidnik kept his victims becomes the model for the well in that film.
But the story most worth telling is not Heidnik's. It belongs to Josefina Rivera.
She spent 4 months in a basement. She endured things no words can fully describe. And instead of breaking, she thought. She planned. She waited for the right moment with a patience that must have cost her everything. When that moment came, she took it — and she brought 3 women home alive.
She is not talked about the way she should be. The case is remembered for its horror. It should also be remembered for the woman who ended it.
