Secrets Of Palm Beach

A Socialite's Secret Love Life Leads To Murder

(CBS)  Bell admits things weren't looking good and that this was a scary time for him. "I didn't know what was going on," he says.

Detectives questioned Bell, but when they realized he really had no motive, and didn't even know where Linda lived, they released him.

"From start to finish, it was like a rollercoaster ride," Keith recalls.

And there seemed to be no shortage of men from Linda's past to question. "And through investigation, it led us to a person named Donnie Saxon who the previous New Year's Eve, had actually spent the night over at her house," Keith explains.

Saxon was a man Linda had met during a night out in Palm Beach several months before her death.

Investigators brought him in for questioning. "Basically, he told us during his interview, 'The funny thing is I had another girlfriend that was murdered.' I think he said it was 30 years previous out in the Las Vegas area and I think it was an unsolved case. It may have been mob related or something like that. So here he is. And he's got another woman in his life that was murdered in the past," Keith recalls. "Now we have not one, but two people with circumstances of violence overshadowing them in the past."

"What does her dating history say about her judgment?" Roberts asks Det. Buss.

"That I think, she was a lonely individual," he replies. "But in the circumstances that we found, while doing our investigation, she, more often than not, ran across men that that weren't her type."

And that included men who were not always age-appropriate. Barbara Wolff says Linda had a tendency to go for the younger guys, and Michael Jamrock says it wasn't unusual to see his aunt in the company of a much younger man.

In Linda's case though there seemed to be several young suitors. "It seems like my sister went after somebody that needed her help, or her guidance," Bernice says. "If they asked for help, she always helped them. She trusted too much that was her problem."

"I think her hairdresser knew about some younger men she may have dated. But when it came time to tell her mom, to tell her family members, the ones closest to her, nobody could give us a name," Keith recalls.

One man Linda dated, and at one point lived with, was Frederick Gurney, a massage therapist 18 years her junior. Detectives could never find Gurney, but 48 Hours tracked him down in Texas. He is now unemployed and listed as a sex offender for indecency with a child.

Gurney wouldn't speak to 48 Hours on camera, but did say Linda was always a generous person. He claims he was living in Texas, and nowhere near Florida, at the time of Linda's murder.

Keith was hitting a lot of dead ends, until four months later, in June 2003, he received a bombshell anonymous letter that would turn the Fishman murder case on its head.

Linda was a woman with many secrets, especially when it came to some of the men in her life. There was the financially strapped nephew, there was a former lover, now a registered sex offender, and there were some men she met that could have used a background check.

But then there was the biggest secret of all: a man 27 years' Linda’s junior named Fred Kretzmer. "She kept Fred pretty much below the radar screen. He never really surfaced as far as being a name of someone that we knew that Linda dated or had a casual relationship with as a friend," Keith says.
