A Chicago father says his daughter is Drew Peterson's fiancée, though the young woman denies the claim, according to the Chicago Sun-Times.
Ernie Raines, 53, of Chicago said his daughter was the woman engaged to the ex-cop suspected in the disappearance of fourth wife Stacy Peterson.
"That ain't going to happen," Raines told the paper. "I'm doing everything I can to try to get her away from him. . . . I'd like to say to him: 'Stay away from my daughter, take his ring back and look for his wife before he's out trying to get another young girl.'"
His daughter Christina Raines said she isn't Peterson's fiancée, though a police source told the paper she is. The 24-year-old waitress said she and Peterson are just friends.
Stacy Peterson disappeared last year. Peterson's third wife's bathtub death was ruled a homicide after initially being deemed accidental.
On Wednesday, sources confirmed to FOXNews.com that the former Bolingbrook, Ill., officer was engaged, prompting his missing wife's family to express their shock.
"I’m shocked, but I’m not surprised," family spokeswoman Pam Bosco told FOXNews.com.
Drew Peterson, 54, refused to answer questions about the engagement in an interview with MyFOXChicago.com.
"This is something that’s very personal to me and very private, and until — I really don’t want all this coming out," he told the station.
He told MyFOXChicago.com that "the media has kind of ruined every relationship I've had, so it scares people."
Stacy Peterson was 23 when she disappeared from the couple's Bolingbrook home in late October, 2007. The couple have two children, Anthony, 6, and Lacy, 4.
After Stacy's disappearance, the body of Peterson's third wife, Kathleen Savio, was exhumed, and her 2004 bathtub drowning was re-labeled a homicide.
Earlier this year, Will County State's Attorney James Glasgow issued a statement about the Savio and Stacy Peterson cases, indicating that a special grand jury is still weighing evidence in both.
Drew Peterson remains married, though he met with met with high-profile Chicago attorney Jeffery M. Leving — a lawyer in the Elian Gonzalez case — earlier this year to see what his rights to a split might be.
Leving told FOXNews.com that Peterson had not yet filed for divorce.
Desertion for at least one year is grounds for divorce under Illinois law — though Peterson, as the divorce petitioner, would have to show he wasn't at fault for causing his wife to leave, Leving said.
Ernie Raines told the Sun-Times his daughter met Drew Peterson at a Bolingbrook laundromat and the ex-police officer took her to the "Blue Man Group" show and promised to buy her a car.
