Kathryn Johnston (June 26, 1914 - November 21, 2006)[1] was an elderly Atlanta, Georgia woman who was shot by undercover police officers in her home on Neal Street in northwest Atlanta on November 21, 2006, where she had lived for 17 years. Three officers had entered her home in what was later described as a 'botched' drug raid.[2][3][4] Officers cut off burglar bars and broke down her door using a no-knock warrant.[5] Police said Johnston fired at them and they fired in response; she fired one shot out the door over the officers' heads and they fired 39 shots, five or six of which hit her.[3][6] None of the officers were injured by her gunfire, but Johnston was killed by the officers. Police injuries were later attributed to "friendly fire" from each others' weapons.[2][3][6]
One of the officers planted marijuana in Johnston's house after the shooting.[7][8] Later investigations found that the paperwork stating that drugs were present at Johnston's house, which had been the basis for the raid, had been falsified.[3] The officers later admitted to having lied when they submitted cocaine as evidence claiming that they had bought it at Johnston's house.[7] Three officers were tried for manslaughter and other charges surrounding falsification and were sentenced to ten, six, and five years respectively.
The officers, dressed in plainclothes, approached the house at about seven in the evening.[9] Officers Gary Smith, Gregg Junnier, and Arthur Tesler; who were wearing bulletproof vests and carrying riot shields when they entered the home,[10] announced themselves after opening the door but before entering the house, according to police.[11] Johnston fired a gun after police forced open the door.[9] It was later determined that Johnston fired one shot from an old pistol, and none of the officers were hit by that bullet.[12] The police officers fired a total of 39 shots, five or six of which hit Johnston.[13][14][15] Police injuries sustained in the raid were due to friendly fire and were not from Johnston's gun. The officers were hit in the arm, thigh, and shoulder respectively; they were treated at the hospital.[9]
Prosecutors later said that Smith handcuffed Johnston as she was dying.[16] Johnston was pronounced dead at the scene.[17] Prosecutors accused one of the officers of planting three bags of marijuana in the house as an attempted cover-up after no drugs were found in the house.[4] Smith later admitted to having planted the drugs.[3][6] They had been found in an unrelated case earlier that day.[7] Prosecutors also accused Smith of calling Alex White after the shooting and telling the informant to say he had bought crack cocaine at Johnston's house.[16] According to court filings, before talking to the homicide detective, the three officers involved in the shooting got together to get their stories straight.[7]
Johnston lived alone and had lived in that house for about 17 years.[9][18] Her house was in a crime-ridden neighborhood in west Atlanta.[16] People in the neighborhood speculated that the police had the wrong person, but police denied that they had had the wrong house.[9] Neighbors and family said that Johnston kept a "rusty revolver" for self-defense; another elderly woman in her neighborhood had recently been raped, and drug dealing was common.[11] In the year before her murder, Johnston had installed extra locks and burglar bars.[19]
