Why silence is goldenFormer Will County Coroner Robert Tezak might face additional charges of obstruction of justice after her allegedly threatened the life of his former daughter-in-law, who was also his lover. No matter what happens, Tezak’e Sept. 13 trial on arson charges was postponed Wednesday until October. Tezak, 45, was jailed at the Metropolitan Correctional Center Friday after U.S District Judge Wayne R. Anderson revoked his bond. The former Republican power-broker is accused of planning arson fires that destroyed two buildings: those housing Crest Hill's Galaxy Bowl and the WTill County's Private Industry Council, 225-227 N. Chicago St., Joliet. Tezak was taken into custody last week after federal prosecutors said he threatened the life of Nikki Leber, 25. Leber is Tezak’s son Mark’s ex-wife. The pair divorced in December.
