A man has died after the truck he was driving plunged into a Jackson County lake. The GMC “Jimmy” went into the water last night about a half-hour after it had been reported stolen from a dealership in south Kansas City. Kansas City police captain Rick McClauglin says it had been stolen about a half hour early, and seen ramming other cars. Officers say the man come to the lake surface, then went under again. He was found an hour later and pronounced dead at a local hospital. His name has not been released.
