Sherburne County Jail "Based on the condition of [Autumn's] body, law enforcement believed [she] had been deceased for some time," reads the charging documents, which note Autumn — who had atrophied muscles and significant hair loss — likely died from asphyxiation. An autopsy found fatal injuries pointing to her being asphyxiated, along with wounds to her head.

Kruse also said the Hallows denied her requests to see Autumn, citing fears over the COVID-19 pandemic, according to the documents.
