Oak Park police have arrested a man suspected of forcing his way into a residence in the 1000 block of South Oak Park Avenue and then raping and robbing a 27-year-old woman last month.
Mark Barnes, 43, was tracked by Oak Park police to a motel in the 9300 block of south Cicero Avenue in Oak Lawn and taken into custody without incident, according to a police news release. Oak Lawn police assisted in the arrest.
Evidence found at the crime scene and analyzed by the Illinois State Police Crime Laboratory linked Barnes to the attack, police said.
The victim told police she was housesitting for a coworker on May 21 when the Barnes allegedly knocked on the front door. He asked for a name the victim did not recognize and then left, according to police.
Barnes allegedly returned, tried to engage the victim in conversation and then pushed his way into the residence, displaying a handgun.
He sexually assaulted her and tied her up, according to a police report. The woman was able to free herself and call the police. She was taken to Rush Oak Park Hospital and was treated and released.
Police reported that Barnes was convicted of criminal sexual assault with a firearm in 1997. He also was convicted of armed aggravated kidnapping, according to the Illinois sex offender registry.
He was released from the Illinois Department of Corrections in April.
Barnes most recently lived at 1051 First Ave. in Maywood, according to the Illinois sex offender registry. The registry notes that Barnes “has failed to maintain accurate registration records as required by law.”
The Cook County State’s Attorney’s Office charged Barnes with home invasion, aggravated criminal sexual assault and armed robbery.
Barnes was scheduled for a bond hearing for Monday, June 8, with an initial court date scheduled for June 12 at the Maywood courthouse.
Oak Park Police Chief Rick Tanksley said in the press release that the Chicago Transit Authority’s Office of Security and the Great Lakes Regional Fugitive Task Force assisted in the investigation.
“Crimes of this type are rare in our community,” Tanksley said. “But when they do occur, there are many law enforcement resources the department can all upon to assist us.”
