Allison Maria Castro, 28, moved from Hawaii to Fayetteville, Arkansas, to pursue nursing and was reported missing by her family on September 19, 2022, after they lost contact with her. That same day Fayetteville police found her ex-boyfriend, Kacey Jennings, suffering an apparent drug overdose at his residence and discovered written notes in which he said he had killed Allison and disposed of her body. The investigation shifted from a missing-person search to a homicide probe.

Jennings was arrested on September 26, 2022, and charged with capital murder, abuse of a corpse, tampering with physical evidence, and theft of property. He pleaded not guilty and the case proceeded to trial. Prosecutors say Allison was shot on August 19, 2022, and that her remains were disposed of in multiple locations, including parts allegedly thrown into Beaver Lake. The jury returned guilty verdicts on all counts and sentenced Jennings to life without parole for the murder, plus additional time and fines for the other convictions.

If anyone knew Allison in Hawaii or Arkansas, or has information about her movements in August and September 2022, please share what is known.
