Mart Hanna, a 68-year-old retired Houston police officer, was shot and killed on December 14, 2020, in his Kerrville, Texas neighborhood after a dispute with his neighbor, 71-year-old retired U.S. Customs officer Kenneth Brown. According to the Kerr County Sheriff’s Office, both men drew weapons and exchanged gunfire; Hanna died and Brown was not injured. The Texas Rangers assisted with the investigation.

No arrests were made immediately and the case was referred to a grand jury for review. The grand jury declined to indict Brown, citing self-defense. The case underscores how quickly neighbor disputes can turn fatal, even between two former law enforcement officers, and raises questions about the role of firearms and conflict resolution in civilian disagreements.

Did anyone in the Kerrville area witness the confrontation or have information about what led up to it?
