Trial begins for accused serial rapist Marc Winner

Disturbing new details surfaced in court Friday when an accused serial rapist went on trial in Chicago.

Marc Winner's been charged in four cases, but prosecutors say he attacked several other women. He’s now facing trial for a single alleged incident detailed in court.

"I’m about to be raped ... Call police.”

Those are words an assistant state's attorney says were uttered by a victim, identified in court as JB, moments before they say she was violently raped inside the west side apartment of accused serial rapist Marc Winner.

Prosecutors allege Winner attacked nine women over a 17-year stretch, and that Winner met his victims at his now closed West Loop tanning salon as either employees or customers and that they were drugged or given alcohol before they were sexually assaulted.

Winners defense attorney offered an alternative theory in court.

"The world out there, in the late night, early morning hours is a complicated place,” he said.

Winner is charged with attacks on women in 2009, in 2010 and again in 2012 and 2015.

Opening court today, prosecutors said the attack on JB illustrates what they say is a pattern of criminal conduct.

Trial will resume Monday and is expected to last about a week.
