Classroom life is back to normal this morning (Wednesday) at Goodrich Middle School as well as Belmont and Campbell elementary schools after a brief lock down early yesterday (Tuesday) afternoon. A man, who seemed upset, was seen carrying a gun around 12th and Belmont. Police Capt. Michon Morrow told KFOR NEWS that the man was very intoxicated. An investigation revealed that the pistol was a plastic BB gun. The 52-year-old Lincoln man was cited for disturbing the peace and failure to comply with police.
