Seven officers and deputies who died in the line of duty were honored at the 10th annual ceremony. Hundreds of police officers attended, including members of the color guard and bagpipers.

The ceremony was expected to begin soon after 11 a.m. The procession left from Morton College in Cicero around 10:30 a.m. and headed west on Pershing Road to Ogden Avenue, and finally to the Cermak Woods Forest Preserve in Lyons.

A procession of squad cars and police motorcycles headed down the road, and the Chicago Police helicopter even flew overhead.

Officers from 60 different departments around Cook County were represented, including the Chicago Police Department, the Cook County Sheriff’s office, suburban police departments, the FBI and the Illinois State Police.

Families of five fallen Chicago Police officers who died last year were to receive memorial plaques at the ceremony.
