David G. Morrison, 30, of Hammond, Indiana, was last seen December 1, 1979. He owned Stereo Components Inc., a high-end stereo store in Munster. Early that morning police responded to a report of a suspicious white car with four men in it; when officers arrived the car was gone, the store door was unlocked and the cash register open. There were no signs of forced entry, but blood was found on a doorframe and on a set of keys inside the store.

A friend later found Morrison’s nearby home ransacked. Police reported blood and hair inside the house and a bloodstained snow shovel. Morrison’s white Pontiac Grand Am with vanity plates STEREO was missing; three days later it was located abandoned in South Holland, Illinois, with bloodstains in the back seat and on the passenger door and Morrison’s driver’s license inside. A body thought to be a white male was seen floating in Lake Michigan the morning of his disappearance but was swept away before it could be recovered. Investigators consider this a homicide; no arrests have been made.

Did anyone in the Munster or Hammond area in December 1979 see the Pontiac Grand Am or the suspicious white car near the store?
