The suspect had parked at a dead end of an undeveloped industrial park in Lorain, located in northeast Ohio, and had an "arsenal of weapons with him," police said.

Data analyzed by the CBS News Crime Unit shows at least 50 law enforcement officers have been shot in ambush attacks so far this year.

Lorain County shooting leaves two officers in serious condition requiring airlift to Cleveland trauma center, while a third officer was taken to a local hospital.
