Rossi claims to have the LP "Johnny's Greatest Hits," by Johnny Mathis, cued up to play next on his record player. However, the next song to play ("I'll Be Easy To Find") comes not from that album, but rather from "Heavenly," released by Mathis a year later.
Rossi says "Well, how about a mint copy of Johnny Mathis' greatest hits on vinyl?" but then he says it's next up to play. Mint condition means absolutely perfect and never played, though some tend to say it only for unopened copies.
JJ states the victim had mostly romance novels but specifically "Nicolae", which is prominently displayed on the shelf, is a book in the Left Behind series by Jerry Jenkins and Tim LaHaye about the Rapture, Apocalypse, Armageddon, and Biblical Prophecy.
