Spoiler Michelle Mellinger, 49, then a special education teacher's assistant, told one 11th-grade student at McKeesport Area High School that he was on her "bucket list." She then took the student home and had sex with him, according to TribLive.com. But she wasn't done. The self-admitted pedophile proceeded to arrange sexual encounters with other students ranging in age from 15 to 17, the news website reports. All told, Mellinger stood accused of having sex with four students. On Monday, she took responsibility for her actions, pleading guilty in Allegheny County to one count of statutory sexual assault, five counts of having intercourse or sexual contact with students and one count of attempted intercourse or sexual contact with a student, TribLive.com reports. In a disturbing twist unrelated to her case, her ex-husband, William Mellinger, 50, was charged with molesting three girls just last week, the news website reports. Meanwhile, McKeesport Area school officials notified police after a staff member heard students talking about Michelle Mellinger. She was placed on leave and banned from the campus, then arrested last October. WPXI reported that at one point, Mellinger referred to herself as being a pedophile in this text to one of her victims: "Wow, you look amazing. I just became a pedophile." On another occasion, she told a student, "I prefer younger people to older people." Now, she faces a prison sentence and a lifetime of registering as a sex offender.
