Just 17 minutes elapsed between the time Fox Lake police Lt. Charles Joseph Gliniewicz first radioed that he was pursuing three suspicious men and when his fellow officers found his body.

The killing of Gliniewicz set off a massive manhunt for the suspects that broadened Wednesday well beyond the northern Illinois village. Here's a brief timeline of what happened Tuesday, according to Lake County Major Crimes Task Force Cmdr. George Filenko:

___

7:52 a.m. — Gliniewicz radios in to say he is checking out suspicious individuals.

7:55 a.m. — The officer calls for backup and reports that the three men — two white and one black — ran into a swampy area.

8:01 a.m. — Two more police officers arrive.

8:09 a.m. — Officers find Gliniewicz's body about 50 yards from his squad car.
