Three teenagers in Florida have been arrested for unleashing “a vicious attack” on a 64-year-old homeless man, with one of the teens telling cops that the victim “dissed” his “dead homies,” according to court documents. Marcavion Lacey, 19, Robert Pope, 17, and Justin Curry, 13, are all charged with murder in connection with the Oct. 19 attack, which left New York native and former World Trade Center worker Roger Borkum fatally injured in a “pool” of his own blood, according to an arrest report filed by the Jacksonville Sheriff’s Office. Borkum had worked as a consultant on the 77th floor.
