Leonard Calogero Moceri, (June 26, 1907 – August 16, 1976) known as Leo Lips, was an Italian American mobster and a member of the Licavoli Crime Family. He got his nickname from his thick lips.
Moceri was born to Giuseppe and Antonia Moceri, relatives of the Licavolis. Pete Licavoli gave him his start selling apples in Detroit. He soon got tired of the job and he held up the local bank. Peter Licavoli was impressed with Morceri and gave him a job as a gunman protecting Licavoli interests in the Toledo, Ohio area. Morceri was charged with murdering Irish bootlegger Jack Kennedy, but was not convicted.
Moceri eventually moved to Los Angeles and ended up working for the Los Angeles crime family. He committed the murder of George "Les" Bruneman with Frank Bompensiero in 1937. In 1951, he was arrested for his part in orchestrating the killings of Anthony Brancato and Anthony Trombino, but was never charged. He was also involved in one of the botched attempts on Mickey Cohen's life, again with Bompensiero. In the 1960s, he moved back to Cleveland.
During his criminal career, Moceri was arrested, but never convicted, for three murders.
