On May 22, 1978, Jerry Martin, 47, and his wife Martha were shot to death through a window screen during a robbery at their home in northeast Columbus, Ohio. Jerry Martin was vice president and general manager of Perma-stone. Valuables were taken from the residence before the attackers fled.

Forensic ballistics later linked the bullets recovered from the Martins to rounds used in a string of other murders in the area. Those killings were committed between December 1977 and December 1978 by brothers Gary and Thaddeus Lewingdon, who became known as the .22 Caliber Killers. A December 1978 arrest of Gary Lewingdon—after he tried to use a victim’s stolen credit card—led to his confession and to charges against both brothers in multiple murders, including the Martins.

Does anyone have memories of the Martins, Perma-stone, or the neighborhood in northeast Columbus from that time who could add details?
