What's the Name of That Book??? discussion

The book is about the solving the robbery/murder of of drug dealers. At least two people, a man and a woman, were killed. May have been another person as well, I don't remember clearly. The book mainly is about the lead detective or prosecutor getting the main witness to talk about it. The witness, an attractive white woman, was a minor participant in the crime. The difficulty is that she lies. A lot. It takes multiple interviews with her to finally get her to tell the truth about what happened. Possibly disgusting detail: (view spoiler)[The drugs were hidden in a plastic bag in the female victim's vagina. The witness was made to pull them out after the killings by the shooters. (hide spoiler)]
A couple of other details:
The witness, years earlier, was raped by 2 soldiers. She refused to press charges against them because they might get the death penalty if convicted.
The investigator took the woman to a restaurant or club to try and get her in a more relaxed state of mind. While there, a local ADA tried to pick her up and had to be warned off by the investigator.
Book probably came out back in the 80s.

Hope springs eternal. It's been a month, so back up top.

Maybe Unveiling Claudia by Daniel Keyes. It's about the .22 caliber murders in Ohio in 1978. I read it long ago, but I think I remember the "disgusting detail."

Beverly, I believe that's it. Thanks muchly. I'll leave this here for a day before moving it to the solved section.

Yeah! This is my first find! We just had to get to my genre.

Unveiling Claudia: A True Story

Forgot to add this to the thread and shelf.

Actually it looks like you did shelve it in 2013.

But when you search for it on the bookshelf page, it doesn't show up as grayed out, which it should since it was shelved. Heinous bug.

I know, weird.
