92-year-old killed in 'roughest neighborhood in Georgia'

ATLANTA, Georgia (AP) -- Many people on the run-down northwest Atlanta street where Kathryn Johnston lived fortify their windows with metal bars and arm themselves for protection.

Johnston, 92, was no exception.

Alone in her home, she was waiting with her gun on Tuesday night when a group of plainclothes officers with a warrant knocked down her door in a search for drugs, police said.

She opened fire, wounding three officers, before being shot to death, police said.
