Editor's note: Channel 3 does not normally identify rape victims. In this instance, Allyssa Allison has chosen to tell her story.

CLEVELAND -- For more than 20 years, Allyssa Allison has been looking over her shoulder and carrying a weight.

She feared that the man who raped her was still out there and could come back and attack her again.

But this week she got some closure. A DNA test on an old rape kit identified her attacker.

Twenty years ago, Allyssa told Channel 3's Tom Beres her story.

A masked gunman ambushed her in her west side apartment and forced her to take drugs.

She was outraged and worked hard to help detectives working her case. She even brought her bedding down to the Justice Center as evidence.

At the time she chose to stay anonymous.

She said, "He told me to take my clothes off. ... He raped me with a gun to my head the whole time. ... I'm a wreck."

But now she's openly speaking about her ordeal.

She's been in counseling for 20 years, crediting the Rape Crisis Center with helping her cope.

This week, she got the breakthrough news. The rapist was the man she suspected, her then landlord.

His DNA sample was in the DNA bank. But investigators got a sample from his son to compare.

DNA tests had linked him to the rapes of three other women.

But it turns out he's dead.

"He's not out there any more. He's not raping other women. ... I can't tell him off. I can't say what I want too. ... He's in his own private hell," Allyssa said.

Allyssa live near Gina DeJesus's family. She says she's motivated by the strength of three women held by Ariel Castro.

She says you don't know what you're capable of until you're tested.

She hopes telling her story inspires other victims.

Prosecutors say the cases involving the deceased serial rapist are closed. But they believe more victims could be found as more kits are tested.

"Without question there could be more hits," said Brian McDonough, who heads the DNA Cold Case Unit for Prosecutor Tim McGinty's operation.

So far the tests have brought indictments in 56 cases, with 67 defendants and 85 victims.

Allyssa is one of those.

She says, " I have three words. It's about time. It's about time."
