The sister of a man arrested July 17 for allegedly dealing drugs at a South Austin Boulevard three-flat was herself arrested just a week later on a parole violation.

Darlene Tolliver, 46, of 112 S. Austin, was arrested last Friday, July 24, one week after her brother, Tyshune Tolliver, 29, was arrested at the residence for carrying drugs. Four others were arrested July 17; all reportedly were living in the three-flat apartment building.

Police went to arrest an armed robbery suspect living at the residence, Antonio Ray, but were forced to barricade the building after he refused to come out. After about an hour, he surrendered to police.

Darlene Tolliver is the sixth person arrested from the three-flat, which is located in Oak Park along Austin Boulevard. Police say she stopped a person from bringing to police a bloody T-shirt allegedly worn by Ray, 39, during one of his robberies. In that incident, a witness struggled with the robber, bloodying his shirt.

“Someone found the bloody T-shirt the [robber] used,” said Det. Sgt. Art Borchers. “The person was going to bring it over to the Oak Park police department.”

Borchers said Darlene Tolliver heard about it, confronted the person and seized the T-shirt. “She grabbed the T-shirt and threw it away. We can’t find it,” he said.

Police declined to pursue obstruction of justice charges against Tolliver, but it was later determined that she was wanted by the Illinois Department of Corrections on a parole violation. She was paroled in April from Lincoln Correctional Center, where she was serving a two-year sentence after a 2008 conviction for two counts of drug possession.

Borchers maintained that police have a strong case against Ray without the T-shirt and blood evidence.

“It’s something that would have been nice to have, but it’s not a huge piece of evidence,” he said.

Also last Wednesday, police said two more witnesses identified Ray as the person who threatened them with a box cutter.

Ray is now charged with four armed robberies in Oak Park between June 7 and July 9-two at an ATM on the first block of Madison, one on the first block of Pleasant Street in Oak Park , and one on the 200 block of North Austin. Ray, who was previously held on $500,000 bond, is now being held without bail due to a parole violation warrant in Alabama for robbery, burglary and battery convictions there.
