Gaby Luonga Kombe, 42, was last seen in Montréal on August 23, 1999. He had gone to the Pie-IX metro station to meet a friend and later that evening phoned his son to say he was on his way home; that call was the last contact his family had with him. At the time he disappeared he was described as 5 feet 9 inches, about 148 to 150 pounds, medium build, with black hair and brown eyes.

The case remains an open and unresolved disappearance handled by the Service de police de la Ville de Montréal. Beyond the planned meeting and the final call, the circumstances of what happened after he left the station are not known.

If anyone in Montréal around August 23, 1999 remembers seeing Gaby or has information about his movements that day, please share what you know.
