The Springfield Police Department began an investigation of DePalma's death after an
autopsy could not reveal a cause of death. Her remains and clothing showed no evidence of bone fractures, bullet wounds, or knife strikes. No drug paraphernalia was found on or around the body. For undisclosed reasons, the coroner suspected that
strangulation was the cause of death, Early in the investigation, Springfield police received a tip regarding a homeless man living in the woods near the quarry. This man was known to locals simply as "Red," and it was alleged that he fled his campsite in the woods shortly after DePalma went missing. While this lead initially looked promising, the Union County Prosecutor's Office ultimately decided that "Red" had nothing to do with DePalma's death. Investigators continued to attempt to find leads, but due to a lack of tips from the public, along with inconsistent stories told to the police by her family, friends, and peers, the case eventually went
cold. Despite rumors and innuendo offered by Springfield police regarding DePalma possibly dying as the result of a drug overdose, no drug paraphernalia was found on, near, or around her body, and she was not known by friends or family to have used any recreational or prescription drugs other than occasionally smoking marijuana socially. DePalma's autopsy report makes no mention of the possibility of a drug overdose, and medical examiner Bernard Ehrenberg went on record stating he suspected strangulation, as he could not rule it out during the autopsy of her remains. ==Possibility of human sacrifice==
