In November 2012, Paul Heenan, a Madison native who had recently moved back to the city, returned home intoxicated after a night out and mistakenly entered a neighbor’s house two doors away. The neighbor, Kevin O’Malley, recognized Heenan and tried to walk him home, but Heenan resisted and the two began fighting. O’Malley’s wife called 911.
Heimsness arrived on the scene with his gun drawn, ordering the two men to “get down.”
O’Malley stepped aside, but Heenan reportedly advanced toward Heimsness. The two engaged in a brief physical struggle and separated before Heimsness fired three shots into Heenan’s torso, killing him at the scene.
