Dangerous Liaisons

How Far Would You Go For Love?

(CBS)  At first their relationship was passionate, says Tracey, but soon they began arguing. Tracey says all the trouble started one wild night in Tampa’s party district, Ybor City. That’s when he and Sandee got caught fooling around in his boss’ Mercedes.

"Tampa Police caught us in the SUV and I was laughing. I thought it was funny, but they saw her naked, and that made her mad," Tracey recalls.

That embarrassing incident led to another big argument - and Sandee and Tracey went home with other dates that night.

"Over the next week, I paraded around a couple other girls that I hooked up with, right in front of her and made her pretty mad," says Tracey.

The relationship spiraled down hill from there.

"I said I thought we needed to take a break, really look at this and maybe spend some time apart," says Tracey.

But unwilling to give up a good thing, a couple of days later, Tracey went home with Sandee again.

"We did what did most of the time - we had sex," Tracey recalls. "She liked to be roughed up during sex, so we had what was normal between us."

But a bruised and battered Sandee told friends and family a different story.

"Apparently they started drinking. He got angry and they got into some kind of altercation of some sort and he tried to physically force himself on her. He hit her, she had black eyes," Heather says.

Sandee also told Heather that Tracey had raped her and threatened to kill her and her daughter.

"She wasn’t sure what to do because she was so distraught over the situation," says Heather.

But because Sandee was so afraid, she waited a week before going to the police to file charges.

Tracey says he was surprised when he was arrested. He insists he did nothing wrong. "She threw a pillow at me, and I swung it at her and it hit her on the side of the eye and it knocked her contact out. She fell face down on the bed," he says.

But to Sandee's sister Tracy Havlicek, there was no question in her mind that she was raped and beaten. "He tied her up, he squeezed her head between his legs, while he was straddling her and punching her face several times," Sandee's sister says.

"He did beat her up. She did have a black eye," says Detective Scott Golczewski. "There were also allegations of sexual battery."

But there was no DNA or medical evidence, because Sandee had waited too long file a police report. Instead, Tracey was charged with assault, which carried a ten year sentence, a prospect that utterly terrified him.

"Tracey told me that before he went to jail he’d commit suicide, kill himself," says Hector.

And that is when, police say, Humphrey hatched a diabolical plan to make his problems disappear - a plot that would involve seduction, manipulation and murder.
