TINLEY PARK, Ill. (AP) — Authorities say a man arrested by the U.S. Marshals Service on a parole violation is just one of many leads investigators are pursuing in the fatal shooting of five women, including one from South Bend, at a suburban Chicago clothing store.

But media reports indicating a suspect has been identified or arrested in connection with the case are "incorrect," Tinley Park Police Department Cmdr. Rick Bruno said Wednesday.

"We can confirm that the U.S. Marshal's office picked up an individual on an unrelated warrant," Bruno said in a statement. "That person was not turned over to the South Suburban Major Crimes Task Force or to the Tinley Park Police Department. However, we consider the information a lead, and treat it as we treat all the other leads that are being pursued."

Several Chicago news organizations, citing law enforcement sources, reported that a man picked up by the U.S. Marshals' fugitive task force in Chicago on a parole violation early Wednesday morning fit the description of the gunman in the Feb. 2 slayings at a Lane Bryant store.

Some media reported that a suspect had been identified, prompting a rush of questions for Tinley Park officials, according to Mayor Edward Zabrocki.

"It's one of the 500 tips we're pursuing," Zabrocki said. "He's not the first guy we've talked to and he's not going to be the last."

"This is creating such a crazy firestorm it's unreal," Zabrocki added.

The department has received hundreds of tips but none is more promising than any other, Bruno said.

The attack at the clothing store left five women dead and another injured.

Killed in the shootings were: Jennifer L. Bishop, 34, of South Bend; store manager Rhoda McFarland, 42, of Joliet; Carrie H. Chiuso, 33, of Frankfort; Connie R. Woolfolk, 37, of Flossmoor; and Sarah T. Szafranski, 22, of Oak Forest.

A police sketch of the gunman, based on a description from the survivor, has been released and is displayed on electronic billboards in the Chicago area. Police describe the suspect as a black man, between 5 feet 9 and 6 feet tall and between 200 to 230 pounds with thick braided hair and a receding hairline.

Also on Wednesday, an attorney representing Woolfolk's estate said a Cook County judge issued an order preserving security records from the Lane Bryant store and the strip mall where it is located, along with all investigative records from Tinley Park police, Illinois State Police and the FBI.

"It is imperative that we secure any and all records and information pertaining to this horrific killing in order to properly protect the legal rights and interest of Ms. Connie Woolfolk's minor children," attorney Thomas Demetrio said in a statement.
