Norman Donald Ball, 69, was shot and killed in his Le Roy, New York, home in the early morning hours of December 1, 2015. A longtime resident of Selden Road and a U.S. Air Force veteran who served during the Vietnam War, Ball was described as a caring father and grandfather who often hosted gatherings at his house.

Police say a neighbor, Kyle Johnson, entered Ball’s home through an unlocked back door and shot him in the head with a 12-gauge shotgun while Ball slept. An altercation between the men earlier that morning is reported to have preceded the shooting. Afterward, Johnson returned home, set his residence on fire and fired shots at firefighters as they arrived. Investigators uncovered a history of mental health issues for Johnson.

Johnson was arrested and charged with second-degree murder, third-degree arson, first-degree burglary and first-degree reckless endangerment. Did anyone in Le Roy know of tensions between the two men or have information about what led to that morning’s confrontation?
