TROY, Ohio (AP) — Authorities in Ohio said they have closed the case on a six-decade-old homicide of a woman whose remains were found in a gravel pit and a canal channel.

Miami County Prosecutor Anthony Kendall approved closing the case based on data from a key witness to the 1964 murder of Daisy Shelton and statements from a suspect, the Miami County sheriff’s office said Friday. Both the witness and suspect are now dead.

A fisherman pulled a severed human arm from a gravel pit east of Tipp City in June1964, and four days later another fisherman found a burlap bag in a channel of the old Miami Erie canal containing a dismembered human torso, authorities said. A head and leg were later found in the canal.

The sheriff’s office said the remains were identified as those of 43-year old Daisy Evelyn Shelton of Dayton, but the investigation went cold until 2017 when a witness who feared he was dying in a hospital confessed to a nurse. He later recovered and told detectives he saw someone kill Shelton by hitting her in the head with a hammer.

The person named as a suspect was interviewed by detectives and initially denied knowing Shelton despite their living on the same street and working for the same employer, but in August 2017 “reluctantly admitted” to having known the victim.

The suspect died in 2022 at age of 92.
