CHICAGO (WBBM NEWSRADIO) — Tinley Park police said last week’s 10th anniversary of the Lane Bryant massacre has prompted some new tips in the case.

Tinley Park Police Chief Steve Neubauer said that between Friday and Tuesday afternoon, 40 potential leads have been called in or emailed to his department.

Neubauer said that, on a normal week, his department receives one or two tips about the five women who were killed and one who was wounded in the Lane Bryant store on 191st and Harlem.

Each of the new tips is still being checked out.

“Many of these tips, you know, people name a suspect and then we’ll find that suspect was in jail someplace when this occurred, so all that kind of background has to be done. It’s very tedious and it’s a lot of work,” Neubauer said.

Last week, Tinley Park police released a new 3-D image of their suspect in the hopes of prompting new tips. The chief said many of the new tips “are related to the new drawing.”

He said each of the leads is being checked out by the one full-time detective and one-part-time detective working to solve the massacre.
