The first day of the search for the suspects in Lt. Charles Joseph Gliniewicz’s death saw sweeps of homes, railroad tracks and marshland in the village of Fox Lake. He expected results from the lab would be available before the holiday weekend.

Investigators are getting an influx of significant leads and believe there is a good probability the suspects are still in the area of Fox Lake or surrounding communities, Filenko said. Filenko noted the videos are being put into chronological order and “there’s a commonality” between them.

Though some officers were nearing the end of their shifts when the Wednesday night manhunt began about 9:30, Covelli and Filenko said they’ve had no trouble finding enough officers to assist in the search. A county sheriff’s spokesman says a woman lied to authorities about seeing two suspicious men in northern Illinois near where a police officer was fatally shot, a report that prompted a large police response.

Asked how unsafe the suspects are, Filenko replied, “They shot a police officer, so I think that speaks for itself – extremely risky”.

Detectives later learned the woman, 30-year-old Kristin B. Kiefer of Vernon Hills, had fabricated the account, Covelli said. “This redirected the entire focus of this investigation for about five hours”, Lake County State’s Attorney Mike Nerheim said at a court hearing Thursday for Kiefer. “We lost a family member”, Schmit said of the 52-year-old officer known around town as “GI Joe”.

Investigators brought in a highly specialized K-9 from the ATF, but it wasn’t the dog who found the evidence, instead it was police officers crawling through the crime scene.

Meanwhile, two detectives have been assigned to filter through the large influx of tips coming in from across the country, Filenko said.

On Friday, officials said Motorola is offering the reward in the death of Lt. Joe Gliniewicz. A source involved in the investigation told on Thursday that Gliniewicz’s gun was sacked, though it’s not clear who pulled the trigger.

More than 100 officers were canvassing the Fox Lake area Friday, revisiting areas and searching new territories. Lt. Gliniewicz was patrolling Fox Lake, Illinois, a mid-sized suburb around 50 miles north of Chicago.

The videos include recordings from homes and businesses in the area; both before and after Gliniewicz was killed.
