A Socialite's Secret Love Life Leads To Murder

(CBS)  In court, Kretzmer said he returned to Linda's home to "rekindle" an old friendship, that there was no sexual contact in the context of the crimes that he committed, and that he wasn't interested in money when he went to her home.

"And, she came out of her bedroom and that's where I seen her for the first time," Kretzmer told the court. "She was frightened because she didn’t have any recollection of me. She didn’t recognize me."

That's when Linda threatened to call police. The walls were closing in on Kretzmer. After a week in which he alienated old friends and savagely beat that store clerk, Kretzmer knew he could go back to prison and panicked.

"I was caught, very, very emotionally and I didn't know what to do, so I went at her and I took her from behind," he told the court. "I strangled her."

"There was no struggle. It was more, she was turning to move away, still just in a threatening way, just loud, yelling and upset, very upset," he recalled.

He also talked about pouring alcohol on her hands and neck because he had touched her to cover the crime scene. And he says he tried to close her eyes; when that failed, he covered her face with an arm chair cover.

Just before sentencing, Kretzmer offered a surprising apology to Linda’s family, saying, "I’d just like to apologize. I don't know where you are sitting out there. I’m sorry."

Michael Jamrock also received an apology from Det. Keith. "I did what I had to do. Was I wrong? Yes. Did I apologize? Yes," he says.

But no amount of apologies will ever really be enough for Michael Jamrock, who lost so much more than his aunt that night; he lost his family. "I'm a perfect example of family just throwing you right in front of a bus," he says. "What they did is just -- it's unspeakable."

"Do you thank God that you're walking, a free man?" Roberts asks Jamrock.

"I just always think of my aunt. And I always think that how strong she was and how positive she was," he replies. "As bizarre as it may seem, I don't think she would have ever allowed it to happen. She's taken care of me my whole life. You know, call Auntie Linda. And everything's gonna be all right."
