DA: Brian Nichols was not delusional

ATLANTA, Nov. 5 (UPI) -- Brian Nichols, the man who allegedly went on a killing spree in an Atlanta courthouse, is not crazy, prosecutor Clint Rucker said.

Making his closing remarks to a jury, Rucker said jurors should reject Nichols' plea of not guilty by reason of insanity to four murders and other crimes, The Atlanta Journal Constitution reported Wednesday.

"It didn't have anything to do with insanity -- or delusion," Rucker said. "The defendant was angry and he was frustrated."

Rucker added that Nichols is "cold blooded" and "remorseless and he is extremely, extremely dangerous."

Nichols, 36, has said he was suffering from a delusion that he was leading a "slave revolt," prompted him to escape from custody at the Fulton County Courthouse on March 11, 2005.
