Investigators are analyzing "significant" home surveillance footage that may show the three suspects in the fatal shooting of an Illinois police officer, officials said Thursday.

A homeowner turned over the security video Wednesday night after seeing "individuals" on it matching the description of the suspects near where Fox Lake Police Lt. Charles Joseph Gliniewicz was killed Tuesday, George Filenko, commander of the Lake County Major Crimes Task Force, said Thursday.

"The homeowner felt it was relevant to turn this over to us," Filenko said, adding that a Department of Homeland Security lab is using special technology to view the surveillance hard drive and could finish analyzing it as early as Thursday evening.

Gliniewicz, a 30-year police force veteran, was found shot to death at around 8 a.m. Tuesday after chasing three people near an old cement plant, according to police. Officials believe whoever killed him is familiar with the remote area, and is likely still close by.

“We’re presuming there is a good probability that they’re somewhere in the area,” Filenko said Thursday.

The lieutenant’s handgun has been recovered, Filenko added, and is being analyzed. It wasn’t clear whether the gun was used in the shooting, but the suspects should be considered dangerous regardless.

“I would consider anybody who murdered a police officer as being extremely dangerous,” he said.

Authorities have been overwhelmed by "an influx of significant leads," Filenko said.

But the investigation was sidelined Wednesday when a woman claimed she saw two suspicious men in a cornfield in Volo, about five miles south of Fox Lake.

Officers, K-9 units and air support spent five hours searching the scene of the sighting, only to have Kristin Kiefer, 30, admit that she made up the report to get attention from the family that she nannies for.
