Officials on Friday are expected to review home surveillance video a resident claims may aid in a search for three suspects believed to have killed a veteran Fox Lake police officer this week.
News of the video first surfaced during a Thursday press conference when officials said that the "significant" footage had been turned over to the Department of Homeland Security for verification.
Details surrounding what was on the footage weren't immediately clear, but Lake County Major Crimes Task Force Commander George Filenko said the resident who turned it in claimed it is consistent with the story about three suspects.
A press conference was held at 12:30 p.m. Friday, where a "change in strategy may be discussed," according to Detective Christopher Covelli with the Lake County Sheriff's office.
Authorities announced an FBI-led tip line (1-800-CALLFBI) and website (www.fbi.gov/foxlake) have been set up for tips in the search. Police said Motorola Solutions is offering a $50,000 reward for any tip that leads to the apprehension of the suspects.
Filenko said the three suspects accused of killing Lieutenant Charles "Joe" Gliniewicz are believed to still be in the area, about 60 miles north of Chicago, and authorities say they've made "significant progress" in their search.
"Obviously we have a lot of transportation means in this area — trains, cars, buses — we’re still working off the fact that we’re presuming there’s a good probability that they are still somewhere in the area," Filenko said. "Now whether they're in Fox Lake or any of the surrounding border communities that remains to be seen."
Filenko confirmed the officer’s gun was recovered, but he didn't say if it was retrieved at the scene, or used in the shooting.
The gunmen are described as two white men and one black man, but further details on their descriptions have not been made available.
Officials expect lab results on evidence gathered at the crime scene to be released as early as Friday morning.
More than 100 officers were canvassing the Fox Lake area Thursday, revisiting areas and searching new territories.
The updates came after a "disappointing" night for authorities, when more than 100 officers spent about five hours searching an area following a tip that was determined to be fake.
"[Wednesday] night was an unfortunate incident," Filenko said. "It tied up a number of resources, including my detectives."
Covelli said the response shows the Fox Lake community that officers are working to keep them safe.
"It really shows that we are here and we are active in this community," he said. "We are active to keep the residents in this community safe... Things will never be quite normal here in Fox Lake with the death of Lt. Gliniewicz."
Residents, family members and officers from Fox Lake and surrounding communities gathered Wednesday night for an emotional vigil to honor Gliniewicz, a 30-year veteran of the police force affectionately called "G.I. Joe." A funeral has been scheduled for Monday in Antioch, Illinois.
