FOX LAKE, Ill. - Hundreds of police officers spent the weekend in Fox Lake looking for new evidence and leads in the murder of Lieutenant Joe Gliniewicz.
Monday is day six of the manhunt for the three men suspected of fatally shooting the veteran officer last Tuesday.
Investigators say they are waiting to see if images of the suspects were caught on surveillance video a resident handed over to police last week.
"Significant" evidence recovered at the scene Friday is still being evaluated.
The FBI took the unusual step Saturday of using Twitter to ask for help in the case. The agency sent a tweet asking for new leads in the investigation. They are also encouraging people to call a special (800) phone number to report information. That number is (800) CALL-FBI (225-5324) or tips can be sent to http://www.fbi.gov/foxlake.
Over the weekend, members of the Lake County Sheriff's office were appointed to lead the Fox Lake Police Department.
Lake County Sheriff's office Deputy Chief Michael Keller was sworn in as the department's interim chief and appointed Lake County sheriff's office sergeant Scot Kurek as interim deputy chief Saturday afternoon.
Former Fox Lake Chief Michael Behan retired just days before the murder of Lt. Gliniewicz.
