Richard "Ricky" Kasso (March 1967 - July 7, 1984), also known as The Acid King murdered 17-year-old acquaintance Gary Lauwers in Northport, Long Island, New York on June 16, 1984. Two other teens, Jimmy Troiano and Albert Quinones, were present at the murder, which took place in the Aztakea Woods of Northport while all four were high on what they believed (and was reported) to be mescaline but was most likely either PCP or LSD. The murder became sensational news in the New York area and across the nation due to the torture of Lauwers and alleged Satanic ritualistic aspects of the murder. The murder took place during a period when there was much public concern over the effects of Satanic and occult content in heavy metal music and in role playing games. Kasso was wearing an AC/DC T-shirt at the time of his arrest and was a fan of groups such as Black Sabbath, Judas Priest, and Ozzy Osbourne.
Kasso was the son of a local high school history teacher and football coach at affluent Cold Spring Harbor High School. Several years prior to the murder, his father, Gregory Pitch Kasso, had won the Nassau County, Long Island Football Coach of the Year, awarded by Newsday.
