- "Lenny, God rest his soul, was a moron."
- ―Mickey Cohen
He was Mickey Cohen's brother-in-law and part of the Cohen Crime Syndicate, though Mickey disliked him. He was also general manager of Polar Bear Ice Company which acted as a front for their drug operation by keeping the stolen army surplus morphine in cold storage. Jose Ramez was part of the operation by receiving and later transporting supplies of morphine to distributors like Merlon Ottie and Jermaine Jones. He had contacted by Sheldon to sell the morphine and was given 1/3 of the shipment. However, Lenny broke the deal with Sheldon by selling wholesale instead of doling it out slowly as per agreed. Lenny's sales had attracted the police as the addicts are died of overdose and Cohen wasn't happy about it.
Events of L.A. Noire
Detectives Cole Phelps and Roy Earle investigated the source of the stolen morphine distribution and arrived at the ice company to arrest Lenny. After a shootout in which all of Lenny's goons are killed, Phelps and Earle offered Lenny a chance to surrender, which Lenny refused, knowing that he would be killed for betraying Mickey and would not last in prison. Resisting arrest, Lenny was killed by Phelps and Earle in self defense.
- "Fink" is a 1940's slang term for an informer or tattle-tale. Thus, Lenny's nickname may be a reference to a perceived character trait as well as simply one to his last name.
- Lenny's notion of being murdered with an ice pick suggests the actual 1940 assassination of Leon Trotsky.
