(CNN) -- A man convicted of crimes in connection with Detroit's organized-crime family claims to know where Teamsters boss Jimmy Hoffa's body was buried in 1975. Anthony Zerilli, 85, told New York's NBC 4 that Hoffa was buried in a Michigan field about 20 miles north of where he was last seen on July 30, 1975. "I'm as certain as I could possibly be," Zerilli told the station. "If I had money, I'd like to bet a big sum of money that he's buried (there)." Zerilli said the plan was to bury Hoffa in a shallow grave, then move his body to a different location. The latter part of the plan fell through, and his body was left in Oakland County, Michigan.
