WARSAW – Three suspended Attica prison guards were reindicted this week on charges they beat an inmate in 2011.

A Wyoming County grand jury handed up an indictment charging Sean Warner, 37, of Belfast; Matthew Raddenmacher, 29, of Wyoming; and Keith Swack, 37, of Corfu, with first-degree gang assault, tampering with physical evidence and official misconduct.

All three entered not guilty pleas during their arraignments before County Judge Michael F. Griffith and each posted $25,000 bail to remain free pending further court proceedings.

The trio are accused of beating George Williams in the “C” Block of Attica Correctional Facility on Aug. 9. 2011. Williams has filed a civil suit, and claims he suffered a broken collarbone and two broken legs in the alleged assault.

The three officers initially were indicted in December 2011 but Griffith dismissed that case, ruling prosecutors used improper evidence. Erik Hibsch, 28, of Gainesville, a fourth corrections officer initially accused of taking part in the beating, was not indicted in the new grand jury action. Prosecutors confirmed Hibsch had been granted immunity from prosecution before the second grand jury presentation in the case.

Warner, a corrections sergeant who outranked his two co-defendants, also was indicted a second time with first-degree offering a false instrument for filing. He is accused of preparing a use of force report which falsified the details of the cell block incident.

The suspended officers all rejected plea bargains offered after the first indictment was returned. The proposal was for them to plead guilty to three misdemeanors each with a stipulation they not serve any time behind bars.

Court officials said Griffith will hear motions in the new case April 16.
