LARGO — An elderly Largo man was arrested Tuesday after he went online and tried to arrange a menage a trois with a male detective posing as a woman with a 13-year-old daughter, police said.
On Monday, Largo police detective Corey Monaghan, adopting the persona of a mother of a 13-year-old girl, began a "casual online chat" with William Casey, 74, after learning Casey was attempting to use the Internet to solicit children for sex.
Casey's wife, Dorathy, had discovered a Yahoo messenger chat on his computer Sunday with a user named "nudeteeninga" and reported his activity to police, according to an arrest affidavit. She had filed for divorce in February, and on Wednesday filed a petition for a domestic violence restraining order.
After some online chatting with Monaghan, Casey "turned the casual conversation into a sexual conversation" and "expressed a strong desire to have sexual relations with Detective Monaghan's persona and the persona's 13-year-old daughter," Largo police said. The affidavit says that during the chat, he also "stated that he committed a sexual battery of a child in the past."
On Tuesday Monaghan, who is a member of the FBI's Innocent Images Task Force, arranged via online chat to meet Casey at Taylor Park in Largo at 2 p.m. Largo detective Lara Young posed as the fictional mother, waiting for Casey at the park.
When he showed up at 2:05 p.m., Casey was arrested on felony counts of traveling to meet a minor for sex acts and enticing a parent to consent to a sex act with a child. He was being held at the Pinellas County Jail in lieu of $40,000 bail.
According to Largo police, in a subsequent interview Casey admitted to sex crimes that are decades old. Those admissions are under investigation. Casey has no previous record of arrests in Florida.
