NEW YORK (AP) - Cheerful written exchanges between a police officer and women from his past appeared in a sinister new light when an FBI agent described at the officer's criminal trial how he talked on the Internet about killing and eating the women. "I'm dying to taste some girl meat," Agent Corey Walsh testified Tuesday that New York Police Officer Gilberto Valle told one of the online friends he met who shared an appetite for human flesh. The testimony came on the second day of testimony in federal court in Manhattan for the 28-year-old Queens resident charged with conspiring to kidnap women and illegally accessing a government database to research potential victims. If convicted, he could face life in prison. It came a day after his 27-year-old wife told jurors she fled their home in September with their 1-year-old daughter after discovering that Valle spent hours a night on extreme sexually violent web sites and one that catered to those interested in cannibalism and asphyxiation. In Reno, Nev., she turned over a computer to the FBI that contained hundreds of Valle's emails and instant messages with what the government has described as co-conspirators. To prove the plots involved real women and to counter defense claims that it was all fantasy, the government summoned several women to testify about their dealings with Valle before prosecutors say he wrote about them as potential targets and, in two cases, potential meals. The women included a former high school classmate, two former college classmates and an 18-year-old woman who attended Valle's high school alma mater and said she had no contact with him before he described her to one of his Internet friends as "the most desirable piece of meat I've ever met" and small enough to fit in his oven. But Walsh said Valle's computer had a file titled "Abducting and Cooking Kimberly: A Blueprint," which included a photo of Sauer. Sauer came up frequently as a subject in online chats between Valle and a man in Great Britain who used Moody Blues as a screen name and MeatMarketMan as part of his email address, the agent testified. Walsh said Moody Blues told Valle he had fantasized about cannibalism since he was 6 years old but did not fulfill the desire until 35 years later. In a chat, Valle told Moody Blues he was meeting Kimberly for lunch on Sunday and that she would be "kidnapped in a couple of months." Moody Blues told him he'd "given thought to your ideas about cooking her alive." "Give me some ideas," Valle said. Moody Blues suggested "cutting her feet off and cooking them on the BBQ in front of her." "I suppose that's a possibility," Valle said. You are the one with the experience. Walsh also described communications between Valle and his co-defendant, Michael Vanhise, of Trenton, N.J. He said the two negotiated the price to be paid for a Manhattan teacher to be taken to New Jersey in a suitcase for Vanhise to rape and kill. The government hasn't said what role Moody Blues played in the investigation.
