Nicasio Carmona Fernandez Jr. was 17 when he was last seen in Montclair, California, in March 1984. At the time he was described as 5 feet 5 inches, about 105 pounds, with black hair, brown eyes and crooked front teeth. When last seen he wore a brown and white shirt, blue jeans with a stripe and brown shoes.

His disappearance followed a fight one evening; after the argument he said he wanted to go into an alley, his brother warned him not to go alone, and Nicasio became angry and said he was leaving. He was not reported missing until 1993. Unconfirmed sightings were reported by friends in 1997 in the Montclair and Los Angeles areas, but his whereabouts remain unknown. The Montclair Police Department is handling the investigation.

If anyone knew Nicasio, saw him around March 1984, or has information about the later sightings, please share what is known.
