Fort Leonard Wood spokesman Mike Warren said a man tried to enter the installation through its west gate earlier in the morning. The security guard determined the identification card the man produced didn't look legitimate and told him to leave.
Instead the driver accelerated rapidly and drove through the gate, then led military police on a chase that ended when he drove back out through the front gate, and the St. Robert Police Department began the pursuit.
The pursuit continued on Interstate 44, where the man opened fire with what appeared to be an AK-47 assault rifle. Officers said after puncturing the suspect's tire, he fled on foot and stole another vehicle.
Police said the man was spotted walking into a building at the Missouri University of Science and Technology in the community of Rolla. The university sent an alert at 8:50 a.m. warning that a gunman was seen entering a building that houses classrooms and offices, then noted 15 minutes later that he had left campus.
