Authorities say they used dental records to identify Sladewski, whose body was found Sunday night. Her body was "burned beyond recognition," Lt. Neal Cuevas, a North Miami police spokesman, told the Miami Herald.
Police say she arrived in Miami with her boyfriend on New Year's Eve after visiting her relatives in Dearborn, Mich. Police said she had been living intermittently in Rancho Cucamonga, Calif., for the last couple of years.
North Miami police say that Sladewski and her boyfriend were staying in a Miami Beach hotel during their visit to South Florida.
Sladewski's boyfriend reported her missing Monday, telling authorities he became separated from her at a Miami club over the weekend.
Police have called the boyfriend, who they have not named, a person of interest, according to the Miami Herald.
Sladewski had appeared in the 2003 Playboy movie titled "Playboy: The Ultimate Playmate Search," according to IMDB.
A cause of death hasn't been released.
Anyone with information on Sladewski's death is asked to call North Miami Detective Michael Gaudio at (305) 891-8111 or Miami-Dade Crime Stoppers at (305) 471-TIPS.
