Chicago Mob boss' brother agrees to testify

The Chicago Sun-Times reports:

For months, Michael Marcello passed along key information about a top mob snitch during his 2003 prison visits to his half-brother, James "Little Jimmy" Marcello -- the Chicago Outfit's top boss.

The details about the key witness, mob killer Nicholas Calabrese, were allegedly coming from the man assigned to protect Calabrese from the mobsters who wanted him dead -- deputy U.S. Marshal John Ambrose.


Now, in a stunning reversal, Michael Marcello, once his imprisoned half-brother's eyes and ears on the street, will testify against Ambrose next month, a prosecution filing shows.
