Council Bluffs Police are asking for the public's help identifying three vehicles.
Detectives say the drivers of the vehicles may have witnessed a carjacking following Monday's inmate escape that lead to the death of Deputy Mark Burbridge.
The images of the three vehicles were captured by a traffic camera at an intersection in the area of North 16th Street and Nash Boulevard.
Police are interested in speaking with the occupants of these vehicles.
They are not suspected of a crime, but may have information on what they saw.
Anyone with information regarding the shooting, attempted carjacking at 16th and Nash Blvd., or the carjacking of a black 2015 Nissan Sentra 4-door, is encouraged to call the Council Bluffs Police Detectives at 712-328-4728.
