NORTH MIAMI from www.cbs4.com – The reward for information leading to the arrest of the person responsible for burning an aspiring model and leaving her charred remains in a dumpster has been increased to $15,000, said Crime Stoppers Executive Director Richard Masten.

“We certainly hope that anyone who knows anything about the case comes forward, but they also stand to earn a reward if they have information that will help us break this case,” Masten told CBS4.com. “Sometimes individuals are motivated by the reward and sometimes they do the right thing.”

Surveillance video from a BP Gas station in Downtown Miami exclusively obtained by CBS4 shows a boyfriend desperately searching for his girlfriend Paula Sladewski after he left her at a Miami nightclub.

Sladewski’s body was found burned January 3rd at a North Miami dumpster. Sladewski and her boyfriend Kevin Klym had flown into Miami from Michigan to attend the New Years’ Eve Lady Gaga concert at the Fontainebleau.

A day later the couple partied at Club Space in Miami and that’s when the two got into an argument. Klym was kicked out and left in a taxi back to his Miami Beach hotel. Sladewski is seen leaving the club minutes later with an unidentified man just after 7 a.m. Sunday.

Klym and her family are now trying to piece together the clues and hope anyone who has any information comes forward.

Sladewski’s sister was in South Florida is back in South Florida looking for justice. The words justice4paula.com adorned a shirt Kelly Faris wore.

“It haunts me, it’s constantly on my mind,” said Kelly Faris. “If I’m not doing this, I’m not living.”

Meanwhile, the North Miami police department is working on a composite sketch that will be released soon, said police spokesman Lt. Neal Cuevas.

For Farris, the capture of the perpetrator can’t come soon enough. “It’s sickening what he did,” Farris said. “He needs to be caught before he does it again.”
