The suspects have been described only in vague terms so far as a black male and two white males. That description is based on what Gliniewicz radioed to his dispatcher before he was killed.
Filenko twice described the development as "significant," and said the footage had been turned over to the Department of Homeland Security.
"Homeland Security has got advanced equipment," Filenko said. "This video in particular is on a particular type of hard drive that they have the technology to retrieve it off of."
While it was initially reported that Gliniewicz was found stripped of his gun, and possibly his pepper spray and police radio, Filenko said Gliniewicz's gun had been "recovered" and didn't believe there was now any equipment missing from the scene. While he wouldn't describe the suspects as "armed," he still cautioned the public to be wary if they believe they've spotted any of them.
"I would consider anybody who murdered a police officer as being extremely dangerous," said Filenko, who added that there's a "good probability" the suspects are "still somewhere in the area."
