Danny Liggett, 37, vanished from New York City after a May 7, 1987, incident in Manhattan’s East Village. He lived in Hoboken, New Jersey, held a Ph.D. in education, and was last seen after accompanying a female acquaintance to meet a man named Kissoon Adams to possibly sell a piece of jewelry. Reports say the meeting turned violent: Adams, who used a wheelchair, was fatally stabbed and Liggett fled. Investigators say Liggett threatened the woman not to report the crime, and an arrest warrant for unlawful flight to avoid prosecution was issued by the Southern District of New York.

Authorities believe Liggett went next to Gainesville, Georgia, where he was reportedly involved in a shooting, then left the United States, possibly with help from family and friends and using a fraudulent passport. The FBI has followed leads for years and is offering up to $25,000 for information leading to his arrest. He is thought possibly to have traveled to Southeast Asia, including the Philippines, or to parts of northern Canada; he also had ties to Springfield, Illinois, and Des Moines, Iowa.

At disappearance he was described as 5 feet 8 inches to 5 feet 11 inches, 145 to 160 pounds, brown hair, brown eyes, with a Snoopy tattoo on his left forearm. If anyone has information about his whereabouts, please contact investigators.
