Log injures three in Kansas City

KANSAS CITY, Mo. -- Three people were injured, one critically, when someone dropped a log from a viaduct onto a passing car on Interstate 70, authorities said.

Police said they believe someone deliberately threw the log on the car Monday morning, possibly as a prank. No arrests had been made Tuesday and murder squad detectives were investigating.

"We are calling this an intentional act given the fact that we have witnesses that saw people throwing things off the bridge," said police Sgt. Tony Sanders.

Four people were inside the car, and the log hit the windshield on the passenger's side, leaving a large hole.
