While in prison, Richard Kuklinski claimed to be responsible along with four other men for the kidnap and murder of former Teamsters union boss Jimmy Hoffa on July 30 1975 in a restaurant parking lot in Detroit. The five-man team were allegedly given the contract on Hoffa by Tony Provenzano, a captain in the Genovese crime family. Kuklinski claimed to have been paid $40,000 for the hit. Kuklinski said that he knocked Hoffa unconscious with a blackjack and, while holding Hoffa's chin up, thrust a hunting knife into the back of his head. Hoffa's body was then allegedly placed in the trunk of a car that was then crushed and sold as scrap metal to Japanese car makers. The claims only surfaced after Kuklinski's death in March 2006 in a book by author Philip Carlo and will probably never be substantiated.
Some of vehicles travelling on the street in 1976 were not produced until 1977 or later. The vehicles are as following Chevrolet Malibu (1978), Chevrolet Impala taxicab (1977), a parked Oldsmobile Delta 88 station wagon (1977). A double-parked Ford Econoline didn't have rectangular headlamps until 1979, following a minor facelift.
In the hospital scenes, "Cover Your Cough" posters are visible in the hallways even though that campaign did not start until the 2000's - many years after the film takes place.
In the hospital, there are visual fire alarms in the hallways. The visual fire alarms didn't appear in the buildings until 1990s under Americans with Disabilities Act of 1990.
Deborah Pellicotti: I was working across the street, and uh, Richie would come over every break he had, and he would bring me flowers and candy. And then it got really awkward, because I didn't know who he was, and I just started making any excuse I could to say no. And then one day, out of the blue, he walks in and he tells me I'm making a big mistake. And I didn't know what to say, because he seemed so convinced. So I went out with him.
