The man, Devonte Willis, 20, was on probation for aggravated robbery at the time of the crime.
Willis allegedly pulled out a gun and demanded money and property from a 24-year-old woman who was walking home from the Red Line stop at 63rd Street around 5:40 a.m. Monday.
Willis took the woman’s cell phone and purse and told the her it was not enough, Dibler said. Willis then asked her what she was willing to do to save her life.
The woman began crying when Willis began touching her. He then forced her at gunpoint into a vacant lot and sexually assaulted her twice behind a large container.
He then took her state ID, $13 and a cell phone from her purse and told the woman he now knew where she lived so she should not call police.
The victim then ran home and called 911. Police responding to a flash alert of the offender, who was described as wearing a multi-colored Chicago Bulls skullcap, dark sweater and light-colored jeans, arrested Willis about four hours later on the sidewalk near his home in the 6200 block of South Dr. Martin Luther King, Jr. Drive.
Willis had the victim’s cell phone case with him and admitted to police that he had robbed and sexually assaulted the woman.
A mask that covered part of Willis’ face during the attack was recovered from his apartment and was identified by the victim.
Willis pleaded guilty in April to aggravated robbery and was sentenced by Judge Thomas Davy to 2 years probation with credit for 143 days served in jail
