​Nearly a month after the body of aspiring model Paula Sladewski was found in flames in a dumpster, North Miami Police have finally released a sketch of a man they say witnesses last saw her with.

Sladewski was visiting Miami with her boyfriend, Kevin Klym, to catch Lady Gaga's New Year's Eve concert. That Saturday night, the two went to Club Space in downtown Miami. After a fight, Klym was kicked out, and surveillance video showed Sladewski leaving the club alone around 7:20 a.m.

Witnesses say they saw her leaving with a "black male." Police had promised to release a sketch earlier but said that they didn't have enough information from witnesses to piece it together.

A reward for information leading to the culprit's arrest has been raised to $15,000. Those with tips are asked to call Crime Stoppers at 305-471-TIPS (8477).
