Police officer H.E. Massey (right) watches Tuesday morning as a technician photographs a note left at the Yates Building that read: “Boom! A Bomb Is in the Court House.” Fingerprints were also taken off the receiver that held the yellow lined sheet to the top of the phone box. Police were alerted by an unverified 911 call, notifying them that the note had been found. Additional officers were dispatched to the Duval County Courthouse to examine the grounds.
