he public can expect sirens, helicopters and blocked roads in Chanute this week as law enforcement agencies converge on the southeast Kansas town for an active-shooter exercise.

The mock event is scheduled Tuesday at Neosho County Community College. Police, fire, medical and media units from local and regional agencies will participate.

Officials say the purpose is to prepare, practice and reflect on a response to a major crisis situation.

The exercise begins at 10 a.m. and is expected to last about four hours.
