In September 1931, between the killing of young Vengalli and his acquittal for that death, Coll was hired by Salvatore Maranzano, who had recently crowned himself the Mafia boss of all bosses in New York City, to murder his right-hand man, Charles "Lucky" Luciano.
Coll agreed to murder Luciano for a $25,000 payment in advance and a $25,000 payment on completion of the job.
