On the evening of Saturday, November 22, 2025, officers responded to the 600 block of Ninth Street in Mamou, Louisiana, after reports of gunfire. They found an unresponsive man with a gunshot wound to the neck who was later identified as 41-year-old Kiyochi A. Shaw of Mamou. Shaw was taken to Savoy Medical Center and pronounced dead that night.

Mamou police say the incident began as a domestic dispute between Shaw and his brother-in-law, Quintin Leon Webb, and that the argument escalated to a firearm being produced and fired. Officers recovered a weapon at the scene that was later determined to have been reported stolen out of Evangeline Parish. Quintin Leon Webb, 40, was booked into the Evangeline Parish jail on November 24, 2025, facing a second-degree murder charge and an illegal possession of stolen firearms charge; bond was set at just over $2 million. All charges are allegations pending court proceedings.

Funeral-home postings and obituary notices list November 22, 2025, as the date his family had to say goodbye, with services planned at Mount Pilgrim Baptist Church in mid-December. If anyone saw or heard anything on Ninth Street that evening or knew Kiyochi, please share information that could help the investigation.
