Pontiac (Ill.) Police Officer Casey Kohlmeier was killed when his squad car crashed on I-55. K-9, Draco, also died in the crash.
Police say another car hit Kohlmeier's squad car, which was stopped in the I-55 median turnaround just north of Route 23. The driver of the other car is hospitalized, but a condition is not known, reports WLS-TV.
Kohlmeier, 29, was a six-year veteran of the Pontiac Police Department, and an Air Force veteran.
Multiple law enforcement agencies—local and federal—reportedly responded to the incident, and Aurora Police now say five officers were shot and wounded in the incident that left five workers at the business and the gunman dead. The injured officers are reportedly stable.
