Montgomery, Ohio (AP) - The FBI mourned four agents - the most lost in any operation in the agency's 74-year history - who died when their small plane crashed while they were being led to $50,000 in buried cash by an embezzler.
The plane plunged into a bookstore Thursday in this Cincinnati suburb and burst into flames, killing all six aboard. Four others on the ground were injured.
The plane was en route to the site where CARL H. JOHNSON said he had buried $50,000 embezzled from a Chicago-area bank in 1975.
Looks like they cleaned up old images. You can see the originals here.
