Dorothy McCann, 77, was found shot to death on February 13, 1978, inside her son Robert Mickey McCann’s house at 4187 Ongaro Drive, a semi-rural area just outside Columbus in Franklin County. Her death occurred alongside two other victims at the same scene: her son and his 26-year-old girlfriend, Christine Herdman. All three had been shot multiple times, mainly around the face and head, and shell casings from a .22-caliber firearm were scattered at the scene. Telephone lines at the residence had been cut, and investigators reported no clear motive and no immediate suspects at the time.

The killings were associated with a string of similar murders in Columbus and nearby areas during the late 1970s referred to as the .22-caliber killings. If anyone knew Dorothy, her family, or has information about the Ongaro Drive killings, please come forward with what can help the record.
