On the morning of November 2, 2022, 49-year-old Michael Hartmann was shot in his backyard on Smithtown Avenue in Bohemia, New York. At about 6:35 a.m., two people had trespassed onto the property and multiple gunshots were fired. Hartmann was struck once, managed to get back into the house, and his daughter performed CPR, but his wounds proved fatal and he was pronounced dead at the scene.

Investigators later developed leads that culminated in arrests in July 2024. Two men, 22-year-old Oliver Schor of Miller Place and 28-year-old Christopher Fernandez of Sound Beach, were taken into custody—Schor in Lexington, South Carolina, and Fernandez on Long Island—and charged with Hartmann’s murder. Prosecutors allege the pair were armed with rifles and intended to enter through the back door; they encountered Hartmann in the yard, and Schor allegedly fired the fatal shot. Authorities say the shooting appears to be a case of mistaken identity.

Does anyone who lived in the area that morning or who knew the Hartmann family have information that could help the ongoing investigation?
