A law enforcement official says a police officer’s estranged wife alerted the New York authorities about her husband, who is now suspected of plotting to kidnap and cook his girlfriend and maybe as well as 100 other women. The official says that Gilberto Valle, 28, an officer in the 26th precinct in Manhattan, was separated from his wife, Kathleen, and she contacted the authorities when she discovered alarming material on his computer. According to the official, FBI and Internal Affairs officers with the NYPD seized Valle’s computer and uncovered explicit messages regarding the plot. The official said these messages were exchanged with people in other countries and were sent from a fetish chat room. Valle also allegedly accessed a law-enforcement database without authorization, reportedly developed his own database -with photos- of 100 potential victims, and had begun staking out their homes and business. Valle who was arrested on Wednesday after a 3-month investigation, is awaiting arraignment in a federal court. He is not known to have participated in any of the acts he talked about.
