KANSAS CITY, Mo. (AP) _ A reputed organized crime leader from Chicago was sentenced today to 28 1/2 years in prison for his conviction on charges of skimming untaxed gambling proceeds from Las Vegas casinos.

John P. Cerone, 71, described by the government as the underboss of the Chicago mob, was the first of five men convicted on Jan. 21 to be sentenced by U.S. District Judge Joseph E. Stevens Jr.

Stevens ordered a four-year term on a count of conspiracy plus 3 years on each of seven other counts of traveling in interstate commerce to carry out the alleged conspiracy. The sentences are to be served consecutively.

The maximum prison sentence on the eight counts would have been 40 years.

Stevens also ordered Cerone to pay the maximum $80,000 in fines, $10,000 on each count; to pay $30,750.50 in restitution to the Nevada Gaming Control Board; and to pay $32,614.73 as his share of the cost of prosecuting the case.

Cerone's attorneys had asked the judge for less than the maximum sentence, saying that anything beyond five years would have the effect of a life sentence on their client.

Cerone and four other reputed organized crime leaders were convicted of conspiring to gain hidden control of Las Vegas casinos and skimming $2 million in unreported gambling proceeds.

Three more defendants are to be sentenced this week: Carl Angelo DeLuna, 58, of Kansas City, who pleaded guilty during the trial; Milton Rockman, 74, of Cleveland; and Angelo LaPietra, 66, of Chicago.

The sentencing of Joseph J. Aiuppa, 78, the alleged Chicago mob boss, and Joseph Lombardo, 58, of Chicago, was delayed until next month because their lawyers are involved in other trials.

All the defendants except Lombardo have been held in the federal prison at Leavenworth, Kan., since their convictions. Lombardo is serving a 15-year term in Michigan on another conviction.

The case involved allegations that mob interests used influence over trustees of the Teamsters' Chicago-based Central States Pension Fund to gain hidden control of casinos operated by Allen Glick's Argent Corp.

Glick formed the corporation in 1974 with pension fund loans totaling $87.75 million to buy and remodel the Stardust and Fremont casinos. Glick testified at the four-month trial that he later was told he had partners who threatened him with death unless he followed their orders.

Frank P. Balistrieri, 67, the reputed mob boss in Milwaukee, pleaded guilty to two of the eight counts during the trial, but his two sons - Joseph P., 45, and John J., 37 - were acquitted by the judge after the government rested its case in January.

Four others pleaded guilty earlier - Carl Civella and Peter Tamburello of Kansas City and two former Chicago police officers, Anthony Chiavola Sr., and his son, Anthony Chiavola Jr.

Charges against Carl W. Thomas, 53, of Las Vegas, were dropped in return for his testimony. Anthony J. Spilotro, 47, of Las Vegas, awaits trial in the skimming case.
