GERMANTOWN -- Authorities pursuing suspects in the fatal shooting of an Illinois police officer have made "some progress," Lake County Major Crime Task Force Commander George Filenko told CNN on Wednesday night.
Lt. Joe Gliniewicz, a 30-year police veteran, was on his way in to work Tuesday morning, in the cruiser that he had taken home the day before, when he saw three suspicious people, Filenko said. This would not have been unusual as Gliniewicz was the type of officer who considered himself on-duty as soon as he rolled into town, he said.
The lieutenant made the first call at 7:52 a.m. and called three minutes later to request backup. The backup units arrived at 8:01 and found their fellow officer dead, roughly 50 yards from his vehicle, at about 8:09, Filenko said.
Gliniewicz is the 24th officer to be shot to death in the line of duty this year -- and his murder is hitting law enforcement officials hard across the country. Many have expressed fears regarding new vulnerabilities on the job.
Germantown Police Chief Peter Hoell says it's been a tough week.
"It kind of chips away at you a little bit and you`re just not feeling comfortable," Chief Hoell said.
Two law enforcement officials have lost their lives in less than one week.
Gliniewicz was killed on Tuesday morning -- and on Friday night, August 28th, Harris County Sheriff's Deputy Darren Goforth lost his life in what Sheriff Ron Hickman said appears to be "an unprovoked, execution-style killing."
He was gunned down as he fueled his patrol car at a gas station.
"Even though you may not know that person, you still feel that pain," Chief Hoell said.
The incidents have prompted Chief Hoell to have discussions about the murders with his officers.
"Really pay attention to your surroundings. There`s no task that's simple. There`s no task that`s safe. Just be aware," Chief Hoell said.
On Saturday, Milwaukee Police Chief Ed Flynn echoed similar concerns when speaking about the murder of Deputy Goforth.
"It`s a sobering reminder about how vulnerable our officers are as they go about their duties. It`s a terrible tragedy, but it`s just a cold reminder of the ambient dangers of this job," Chief Flynn said.
Flynn spoke about the murder of Lt. Gliniewicz on "FOX and Friends" Wednesday morning.
"Every cop in America is looking over their shoulder right now. There`s no doubt about it. They don`t believe America has got their back," Chief Flynn said.
But Chief Hoell says officers across the country will continue to do their job because it's important.
"We can`t sit back because it could happen in our community any day, so we have to stand up and be vocal for what we think," Chief Hoell said.
The three suspects wanted in connection with Gliniewicz's death in Fox Lake haven't been located.
This, after investigators marked off a two-square-mile area across tricky terrain and brought in helicopters, canine units, federal agents, night-vision equipment and body-heat sensors. Police cleared every home in the cordoned-off area, while fielding more than 100 tips.
The tips are arriving via phone calls and social media from all over the nation, and from as far away as England and Australia, he said, encouraging the public to continue reporting anything suspicious.
Authorities are in talks with the federal government about a potential reward for information leading to the arrests of Gliniewicz's killers.
Gliniewicz was remembered during a vigil in his honor in Fox Lake on Wednesday evening.
