John Constantine, an 80-year-old man from Los Angeles, was last seen on April 4, 1998. That afternoon, around 3:00 p.m., Constantine left his residence in the Rampart Division area with plans to have dinner near MacArthur Park. However, he never returned home and has not been seen since. At the time of his disappearance, Constantine was wearing a short-sleeved yellow shirt, light yellow pants, and yellow sunglasses.

There is a possibility that Constantine may have been admitted to a hospital or care facility, but no concrete evidence has emerged to confirm this. Despite efforts by the Los Angeles Police Department, his whereabouts remain unknown, and the case is still classified as unsolved.

If anyone has information regarding his disappearance, the LAPD's Missing Persons Unit continues to investigate the case.
