Six murders in the past 10 months are linked to a mob war for control of the lucrative stolen auto racket.Carey said the investigation, to be headed by Thomas M. Burnham of Carey’s office, will also look into the slaying of mob kingpin Sam Giancana, shot to death in his home slightly more than two years ago.The task force was formed after Carey met in his office Monday with Police Superintendent James Rochford, Sheriff Richard Elrod, and Tyrone Fahner, head of the state law enforcement agency.The task force will include lawyers and investigators from the state’s attorney’s office, the Chicago Police Department, Cook County sheriff’s police and the Illinois Department of Law enforcement.The most recent crime syndicate figure to be killed was Sam Annerino, 34, shot to death lastweek. Authorities speculated Annerino succeeded south suburban junk dealer Richard Ferraro, 36, as the mob’s director of the stolen car racket. Ferraro dropped out of sight June 13.Attorneys claim diary falsifiedCHICAGO (UPI) — Attorneys for two defendants in a $1.3 million Metropolitan Sanitary District bribery case have charged the key prosecution witness might have falsified some entries in his diaries.The witness, William J. Benton, former senior vice president of Ingram Corp., New Orleans, said he made payoffs to Chicago officials in exchange for $43 million in contracts to haul sludge to Fulton County. Benton’s account is contained in diaries he gave the prosecution.Attorneys tor Ingram Corp. owners Frederic B. Ingram and E. Bronson Ingram filed documents in U.S. District Court Tuesday, claiming forensic tests of Benton’s diary “strongly suggest that the various critical diary entries may have been fabricated well after the fact in order to confirm Mr. Benton’s testimony.”
