Margaret Kay Holst was 18 when she vanished from Omaha, Nebraska, after leaving home on the evening of August 4, 1977. She left a note saying she was going out on a date with a boy she had recently met; that boy later said he dropped her off near her residence after the date, but Margaret never returned and has not been heard from since.

At the time she disappeared she was described as 5 feet 6 inches, 125–130 pounds, with long auburn hair and hazel or blue eyes, a small scar on her forehead and slightly crooked upper teeth. On the night she went missing she wore a long-sleeved red and black shirt, blue jeans, blue sandals, an opal birthstone ring and a gold band engraved with the letter M, and carried a brown imitation leather purse.

Extensive searches and investigations have produced no significant leads, and little information has emerged over the years. Does anyone who knew Margaret, the man she went out with that night, or who was in Omaha near North 25th Street on August 4, 1977, have information that could help clarify what happened?
