Mark David Chapman also says the bullets he used came from a former police officer friend.
Chapman told a New York parole board earlier this month he borrowed $5,000 from his wife's father to pay for his trip from Hawaii to shoot Lennon on Dec. 8, 1980.
The details are in a transcript of his latest hearing released Thursday.
Chapman was denied parole after the Sept. 7 hearing, his sixth since becoming eligible in 2000. He will be up again in 2012.
Chapman told the panel killing Lennon was "a horrible decision." He said he thought killing someone famous would make him somebody but instead it only made him a murderer.
