Authorities investigating the killing of a northern Illinois police officer say they've received several more videos from residents and businesses.
Lake County Major Crime Task Force Cmdr. George Filenko told reporters Friday that he believes the new videos are "even more relevant'' than one received earlier in the week. Some of the new videos came from intersection traffic cameras.
He said he hasn't yet had a chance to view any of them himself because they're being analyzed and processed by the FBI and the federal Department of Homeland Security.
Authorities hope the videos will offer investigators a detailed description of the three suspects they're seeking.
Police Lt. Charles Joseph Gliniewicz was slain Tuesday in the village of Fox Lake, about 45 miles north of Chicago.
