She had no money on her, she had nothing to give when the armed robber held her up at gunpoint in an Upper Darby alley around 8:30 p.m. Jan. 17.

But that didn't stop him.

"You are going to give me something," he said, according to police reports.

With that, the robber took something far more precious than cash from the 19-year-old woman. He took her body.

She made up lies to try and get him to stop. She told him she had a sexually transmitted disease, she told him she was 16 and she told him she was a student at Upper Darby High School but nothing worked, said police Superintendent Michael Chitwood.

"This guy is an animal and we’ve got to get him off the street, plain and simple," Chitwood said.

Although the attacker let the young woman live, her life has been changed forever.

Police said the Tuesday night attack happened in the rear alley of Wiltshire Road near Patterson Avenue. The victim was walking home from a friend's house when the suspect grabbed her from behind and took her behind a bush, demanding money. When he realized she had none, he began performing various sex acts on her and forcing her to perform them on him, police said.

After he was done with her, the man let the woman walk away, but told her not to turn around or he'd shoot her, Chitwood said.

The victim ran home and called police, who located the crime scene and transported the victim to a hospital for evaluation. A state police sketch artist recently drew a composite sketch of the suspect and police are now asking the public to help identify him.

Police described him as a black man in his late teens whose eyes are close together and whose nose is unusually long and large.

Anyone with information is urged to call Upper Darby Police at 610-734-7684.
