Ngeun Thi Long was a 19-year-old woman of Laotian descent who was killed on May 13, 1984, in Tampa, Florida. She had recently moved to Florida from California and left a nightclub job to study art and cinema at the University of South Florida. Her body was discovered by two teenage boys in a field near Interstate 75 southeast of Tampa; the remains were severely decomposed and initially difficult to identify.

She was found face down with her wrists loosely tied behind her back and a noose draped around her neck. The medical examiner determined she had been strangled and suffered severe physical abuse; evidence suggested sexual assault. Tire tracks at the scene later proved useful to investigators. The case was linked to serial killer Bobby Joe Long, who was convicted of multiple murders in the Tampa Bay area during 1984. Did anyone who knew Ngeun in Tampa or California ever see or hear anything unusual around May 1984?
