Playboy Model's Family Points Finger at Boyfriend

Model's text message: "I'm in Trouble, He's Trying to Kill Me"

As police still investigate what might have led to the death of Paula Sladewski, an aspiring model who once posed in Playboy, her family has already started pointing the finger at her live-in boyfriend, Kevin Klym.

Sladewski's stepfather Richard Watkins told Fox News that he has been in contact with one of his stepdaughter's ex-boyfriends who claims she would send him cryptic text messages about being in danger.

He said some of the texts read, "help me, I'm in trouble, he's trying to kill me."

It's unclear if police have seen any text messages from Sladewski about abuse or if she sent any over the weekend while she was in Miami.

Sladewski's body was found burning in an empty trash bin in North Miami.

Klym, 34, reported Sladewski missing on Sunday after the couple was seen in Club Space. Klym told police they got in a fight and he was kicked out of the club, while his girlfriend stayed inside. They both were in town from California to take in the New Year at the Lady Gaga concert at the Fontainebleau.

No one has seen her since she left Space, and police have been looking at surveillance video from the club that night for clues as to what might have happened. Police have also not determined a cause of death.

Authorities have not ruled Klym a suspect, but said he was a person of interest since he was the last person to see Sladewski alive. He has met with police at least four times and his attorney told CBS News that he would submit to a lie detector test if need be.
