Grant Griffiths, 58, was found dead in his Prescott Valley home on Spurr Lane on the morning of May 29, 2023. Investigators determined he had suffered multiple gunshot wounds and that a fire had been set in his bedroom after his death; an accelerant was found on the bed and no smoke was detected in his lungs, indicating he was already deceased when the blaze began. Authorities have classified the case as a homicide.

Detectives have named 58-year-old acquaintance Robin Mark Consylman as a person of interest; Consylman had previously lived with Griffiths and the victim’s daughter has said she found his behavior suspicious. No arrests have been announced. Yavapai Silent Witness is offering up to a $10,000 reward for information leading to an arrest.

If anyone knew Grant, Consylman, or saw activity around Spurr Lane on the night of May 28, 2023, please contact investigators with any information.
