Larry gave the tape to a friend for safekeeping. A year later, it was passed to me with instructions that I wasn't supposed to do anything with it until certain people named in the tape were dead. Those people are gone now. Because of the seriousness of what's being alleged on this tape, we're not going to share their names here.

One day in September of 92, Larry was down at the county courthouse here in Oklahoma City when a man struck up a conversation with him in the elevator. Now Larry, he didn't know this guy from a hole in the wall, but they got to chit-chatting, made a friendly connection. Then a week or two later, Larry ran into this same guy again.

As part of his job, Larry kept something called a daybook. It's where he took field notes on things like arrests and accidents. To this day, Larry has held on to all of his daybooks, along with copies of his accident reports. When we interviewed him in 2024, we asked him to read from the daybook he was keeping in the fall of 1992. I see on...

Larry took these allegations seriously. If they were true, then this was a crime, a big one, possibly a murder case.

So Larry started to sniff around the Oklahoma City Police Department. He was circling some of the same territory that private investigator Joe Royer had been circling around in the late 1970s.

So Larry arranged to meet with his source to get more information, and the source said he knew someone who had even more details about what had happened to Karen. So Larry kept recording.

Larry's investigation went cold. He didn't hear anything back from the FBI until the following year, 1993. That's when he made his last recording. The FBI agent said he'd turned over the information Larry had shared to the Oklahoma State Bureau of Investigation, or OSBI. In April 1993, Larry met in person with an OSBI agent.
