Florida jury convicts man as an accessory to beheading of woman FORT LAUDERDALE, Fla., Jan. 30 (UPI) -- A tree trimmer from New York was acquitted of killing a woman whose head was found in a South Florida canal but convicted as an accessory. Robert Mackey, 44, who was convicted Tuesday, is to be sentenced Feb. 28, the South Florida Sun Sentinel reported. He faces up to seven years in prison as an accessory after the fact. Lorraine Hatzakorzian, 41, of Mastic, N.Y., was slain in 2007. Her head was found in a canal in the Everglades in Broward County. Hatzakorzian left New York with Mackey and Paul Trucchio in April 2007 in her pickup truck. Trucchio pleaded no contest to murder last year. Investigators had little evidence linking Mackey to the actual killing. But witnesses had seen Mackey and Trucchio in the truck after Hatzakorzian's head was found and saw them washing down the vehicle with bleach. Witnesses said Mackey, like Trucchio, had talked about how he had killed a woman.
