Sylvia Cabalic, a 24-year-old nurse who was also pregnant, was found beaten to death on December 30, 1974, in the basement laundry room of her apartment building at 507 Lowell Avenue in Cincinnati, Ohio. She had worked the night shift and reportedly returned home sometime after 7:30 a.m. Friends who could not reach her led police to perform a welfare check that evening, when officers discovered her body.

Neighbors reported hearing noises of a struggle during the attack, but no one intervened. Despite those possible witnesses, no suspects have been identified and the case remains unsolved. The Cincinnati Police Department continues to appeal for information that might help bring justice for Sylvia and her unborn child.

If anyone knew Sylvia, lived in that building, or remembers unusual activity near 507 Lowell Avenue on December 30, 1974, please contact the authorities with any information.
