The indictment adds two murder counts and charges for moving a dead body, failing to report a death, tampering with evidence, and battery. Prosecutors note Amazon purchases of duct tape, trash bags, lighter fuel and fire starter, and a DoorDash cleaning order. Phone data linked the suspect’s Hyundai Genesis G80 to Limon’s phone near the bridge.

Investigators have not identified the human remains recovered on April 26, leaving Bristy’s status unresolved. The medical examiner’s cause-of-death report for Limon is pending. Prosecutors claim Abugharbieh used ChatGPT for disposal advice, but the suspect’s own statements on those queries have not been verified.
