COOK COUNTY CRIMINAL COURTHOUSE — Two women were leaving The MID nightclub in the West Loop shortly after 3 a.m. on Halloween when two men attacked and sexually assaulted both of them, prosecutors said Wednesday.

The victims, ages 29 and 30, left the nightclub at 306 N. Halsted St. and walked to their SUV, which was parked in the 800 block of West Wayman Street, prosecutors said. When they got there they discovered a broken window and possessions missing from inside.

As they stood on either side of the SUV assessing the damage, two men snuck up behind them, each wrapping their hands around the women's necks, prosecutors said.

Greg Bogacz, 27, strangled one of the women until she lost consciousness while his alleged accomplice, who has not been arrested, muffled the screams of her companion, prosecutors said.

The two men forced the women into the SUV, where they sexually assaulted and beat them, prosecutors said.

One of the women was able to escape, prosecutors said. She ran, mostly naked, for several blocks until she encountered several people working outside of a warehouse. They called 911.

Meanwhile, Bogacz's accomplice dragged the other victim by her hair from the SUV to his own vehicle, prosecutors said. A witness allegedly saw him and noted a portion of his license plate. The woman later escaped.

Both the women later identified the men in surveillance video from The MID, prosecutors said. The video footage was provided to the media, and police received multiple tips leading to the arrest of Bogacz, officials said.

Cook County Judge Donald Panarese Jr. ordered Bogacz held on $300,000 bail during a brief court hearing Wednesday. His alleged co-defendant remains on the loose.
