(Update) Puna Man Charged with Murder Following Shooting in Mountain View

On Wednesday afternoon, November 26, 2025, at 1:15 p.m., after conferring with the Office of the Prosecuting Attorney, 40-year-old Joseph Davis was charged with the following offenses:

· Second-degree Murder

· Use of Firearm in a Commission of a Felony

· Place to Keep Ammunition.

Davis’ bail was set at $1,505,000. He is scheduled to make his initial court appearance on Friday afternoon, November 28, in Hilo District Court.

The victim has been positively identified as 52-year-old John Marshall Marrou, of Volcano, Hawai’i. An autopsy has been scheduled for Friday morning, November 28, 2025, to determine the exact cause of death.

The charges against Davis stem from an incident that occurred on Tuesday afternoon, November 25, 2025, shortly after 1:30 p.m., when Puna patrol officers responded to a report of a man being shot multiple times in the parking lot of the Mountain View Mini Mart. Callers also reported that the suspect was still at the scene and in possession of the firearm.

Upon arrival at the scene, officers immediately arrested Davis for second-degree murder. He was transported to the East Hawai’i Detection Facility in Hilo.

Upon arrest, Davis was found in possession of a small zippered bag which witnesses observed him placing a firearm into following the shooting. Davis’ bag and a bicycle he arrived at the store on were recovered as evidence. Area I Criminal Investigation Section detectives executed a search warrant on the bag, and a pistol matching the description of the weapon used in the incident was recovered. A search warrant was also executed on bags on the bicycle and additional ammunition was recovered.

Police ask anyone who may have witnessed this incident to contact Detective Lisa Ebesugawa of the Area I Criminal Investigation Section, at (808) 961-2382, or via email at Lisa.Ebesugawa@hawaiicounty.gov.
