Gary Swiercz was a deputy fire commissioner in Chicago Ridge, having been with the Chicago Ridge Fire Department for more than 20 years.
Prosecutors say he broke into a woman's Tinley Park apartment Saturday, threatened to cut her throat and slammed her to the floor before fleeing.
Because he allegedly wore a mask, the victim didn't recognize the attacker-- and after the attack, she unknowingly went to Swiercz' apartment to seek help, but he was not there.
Swiercz faces multiple charges, including attempted murder.
