Katherine Devine disappeared from her home on November 25, 1973, per the Seattle Post-Intelligencer. She had allegedly had a fallout with her boyfriend and had taken things hard as she began to indulge in substance abuse. In the same period, she reportedly decided to hitchhike to her cousin's place in Rockaway, Oregon.

Her disappearance came after she argued with her mother. She had left behind a note saying,

"PS. Don’t worry mom I’ll be back."

According to Katherine's obituary, she had been depressed and emotionally lost at the time she left home. Kathy loved poetry and decorated her room with snippets of it.

However, the remains found in the area close to Capitol State Forest near Littlerock were not identified as belonging to Katherine until her sister, Sherrie Devine, recognized the embroidered dragon patch on her pair of pants while watching the news on television a couple of weeks later. The remains were in an advanced stage of decomposition, making the determination of the cause of death difficult.

The investigators determined that she had been sodomized, strangled, and s**ually assaulted. A rope was found under her body, and there were deep knife wounds on her chest.
