Walter Lee Brown, a 53-year-old radio dispatcher from Marrero, Louisiana, disappeared in June 1993 after telling his wife he was driving about 250 miles to Holt, Florida to visit a man. He was last seen at his Avenue A home before leaving; the next day his white Ford LTD was found at a rest stop on Interstate 10 in Holt with the keys in the ignition and the car in good running condition. Brown is a white male, 5 feet 11 inches, about 285 pounds, with white hair, blue eyes, and a full beard and mustache; he had scars on his forehead and right hand.

Brown had been working as an informant for the Bureau of Alcohol, Tobacco, and Firearms. Bags labeled ATF Use Only were recovered from the abandoned vehicle containing tapes of recorded conversations in which Brown said he feared for his life and reported threats involving the ATF, the FBI, and the man he planned to visit. His wife filed a life insurance claim soon after he vanished and later moved to Florida. There has been no communication from Brown and authorities have not confirmed whether he drove the car to the rest stop.

Did anyone in the Holt or Marrero area have contact with Walter Brown around the time he disappeared or information about the man he planned to visit in Holt?
