Drew's Showdown with Stacy's "Boyfriend"

"He {Drew Peterson] asked me how I'd react if my wife was with another man," Scott Rossetto said Wednesday after testifying before a Will County grand jury looking into Stacy Peterson's disappearance. Stacy Peterson had told her husband she planned to meet {Scott] Rossetto at the Denny's, Rossetto said.

Drew Peterson told her not to go, and when she defied him, Drew Peterson showed up at the restaurant in his Bolingbrook police sergeant's uniform and sat down at their table. He didn't rant or rave. He was "quiet mostly," Rossetto said.

The 35-year-old registered nurse from Shorewood denies having an affair with Stacy Peterson but acknowledges he traded racy text messages and e-mails with her. "Some of the messages were quite perverted and flirty in nature, but they were all meant in fun," Rossetto said. "[Was I] Interested in dating? No. Flirting? Yes." But police sources dispute that. A source characterized Rossetto as her ''boyfriend.'' The source said the messages were indeed "very sexually explicit," and appear to show them talking about sexual encounters they shared and asking if the other enjoyed it."
