The dismembered body parts of an unknown Oregon woman found along the Willamette River in April 1946 are thought to be the remains of Oak Grove Jane Doe, Oregon state police said on Monday. Authorities said Oak Grove Jane Doe was a petite white woman between the ages of 30 and 50. Oregon state police said the case went cold in the 1950s. “Critical evidence, including the victim’s remains, went missing from law enforcement custody, with no documentation of their disposition,” state police said. A group of fishers who found the torso told local press they initially thought it was a bag of drowned cats.
