Steve Guidry, 67, was killed at his family’s heating-and-air-conditioning business on East Person Avenue in Memphis around midday on Saturday, November 18, 2017. He was found near the office area with multiple gunshot wounds and was pronounced dead at the scene. Investigators believe the shooting occurred during a robbery that began when three men arrived asking for help.

Guidry’s son and co-worker, Cory, followed a dark blue Chevrolet—described as an Impala or a Malibu—in his work van after the men left. The car began driving erratically, running red lights, until Cory lost it and became separated from the business and his father. Witnesses reported a tan or gold SUV near the property and a blue four-door Impala or Malibu leaving around the time of the shooting; surveillance footage supposedly captured the car that drew Cory away, and Cory noted the vehicle had distinctive damage such as a left taillight being out. A hard drive that might have contained clearer footage was damaged in the shooting.

Police later said they had no real public lead and only one tip had come in about the blue car; the case has been described as a cold case and investigators continue to ask for witnesses. If anyone saw the tan or gold SUV, the blue Impala or Malibu, or anything on East Person Avenue that afternoon, can you share what you know?
