Elvis sightings
Sightings of singer Elvis Presley have sometimes been reported following his death in 1977. The conspiracy theory that Elvis did not die and instead went into hiding was popularized by Gail Brewer-Giorgio and other authors. Notable sighting claims. The earliest known alleged sighting of Elvis was at the Memphis International Airport where a man resembling Elvis gave the name "John Burrows", which was the same name Elvis used when booking hotels. A series of alleged sightings took place in Kalamazoo, Michigan, in the late 1980s. Such reports encountered public ridicule and became fodder for humorous publications like  the "Weekly World News". In California, many people believed to have seen Elvis at California's Legoland amusement park shortly after opening in 1999. It was later revealed that Elvis impersonators were hired as an attraction to commemorate the famous singer. Elvis was rumored to have appeared in the background of an airport scene in the 1990 film "Home Alone". It was alleged that the bearded man wearing a turtleneck and a sports jacket who could be seen over the left shoulder of Catherine O'Hara's character while she is arguing with an airline employee was Elvis. Paranormal researcher Ben  Radford responded to Elvis sighting believers with, "Why fake your death and then turn up as an extra in a popular movie? How could the cast and crew have failed to notice the presence of one of the most famous figures in the world? Even if he looked very different, could he have disguised his voice and mannerisms?" Radford was challenged to find the actor who played that part to prove it was not Elvis. He explained that the burden of proof was on the person making the claim. In an interview with "USA Today", director Chris Columbus responded "If  Elvis was on the set, I would have known". After being challenged by Radford to locate the true identity of this extra, Kenny Biddle investigated and found the man to be Gary Richard Grott, who died of a heart attack in February 2016. Biddle located Grott's son, Roman, who explained that his father was indeed the extra in the airport scene of "Home Alone", and that he had known director Chris Columbus personally. Because of this he appeared in a number of his movies as an extra, including "Home Alone". Bill Bixby, who co-starred with Elvis in "Clambake  and Speedway", hosted two television specials investigating the conspiracy: "The Elvis Files" (1991) and "The Elvis Conspiracy" (1992). The conspiracy was also featured in the 1990 video game, "", where the titular hero attempts to find Elvis (known in the game as "the King") to win a million-dollar contest. Some believe that Elvis attended his own 82nd birthday. An old man, with security guards around him, all grey hair, grey beard, sunglasses and a ball cap on, was believed by conspiracy theorists to be Elvis. A similar looking man was seen working as a groundskeeper for Graceland, and was also  believed to be Elvis. A group of people believe that Elvis was somehow involved with the Mafia during his time as a rock star, served as an undercover agent and was found out. Thus, they believe he faked his own death to try and fool the mafia.
