Even people who had never met the deputy came out to pay their respects.
"I wanted to be here for the family, the McHenry County police family and also for his wife," said Sgt. Patrick Donahue, Chicago Police Department.
"We thought it was really important to bring the kids out here (Saturday) and show them how much respect and support we need to show each other," said Eva Crown.
Maness was shot with another deputy as they answered a call for a domestic disturbance in October 2014. His death remains under investigation. If the coroner determines he died as a result of that October shooting, te shooter could be charged with murder.
