Three young adults were found shot to death in a Sioux City home at 1117 Morningside Avenue after they missed work in late 1974. Ernest Billy Isom, 27, known as Billy, his 24-year-old pregnant girlfriend Freta Bostic, and 26-year-old coworker Jesse Hanni were discovered by Billy’s mother on the morning of December 3. Investigators believe the killings occurred between the evening of November 30 and the afternoon of December 1; the bodies lay undiscovered for more than a day.

The scene was violent: Freta was found facedown near the fireplace with a single gunshot wound to the back, Jesse was propped against a door with two gunshot wounds including one behind his left ear, and Billy was nude, facedown and shot five times in the head and back. Police examined leads including small amounts of drugs reportedly found in the house, a coworker who allegedly feared a drug dealer, a couple who left town abruptly and two men who admitted borrowing Billy’s 1974 Datsun; none were charged.

No suspect was ever officially named and no arrests have been announced. Does anyone have information about the Morningside murders or the people involved that could move this cold case forward?
