The Man Who Died on the Toilet...

Rumors have been going around ever since Elvis Presley's death that he is still alive somewhere. Most people believe that he faked his own death so he could live the rest of his life in peace and quiet somewhere away from the maddening crowds of his fans. Elvis Presley supposedly died on August 16, 1977, he had been on the toilet but had fallen onto the floor, into a pool of his own vomit. After the autopsy had been taken place, Elvis' cause of death was said to be "cardiac arrhythmia" but later was admitted to be a hoax made by the Presley family to cover up the real cause of his death. Elvis Presley died of a cocktail filled with ten prescribed drugs.
Although, this seems to be the reason why Elvis died, his fans haven't seemed to accept the truth. People have claimed to spot Elvis all over the world. Speculations of Elvis' fate started back in 1979. That year, the country singer Waylon Jennings wrote a song with lyrics that indicated that Elvis might still be alive. This simple song started rumours and got fans really angry and curious, hoping that he was still alive.
Two tabloid newspapers, the Weekly World News and The Sun, ran articles covering the continuing "life" of Presley after his death, in great detail, including a broken leg from a motorcycle accident, all the way up to his purported "real death" in the mid 1990s. However, since his "real death", the Weekly World News has continued to claim he is still alive, thus contradicting its initial story.
People believe that the body in Elvis' coffin wasn't really him and it was just a figure made of wax I found this on Wikipedia and thought it may be interesting!
10 reasons why the body in Elvis' coffin was fake: (some of the reasons are a little far-fetched but its stil pretty neat information.)
1. Elvis Presley's custom-made coffin weighed 900 pounds. Funeral attendants reported that the air around it was unusually cool, leading to suspicion of a built-in AC unit to keep a wax body (i.e. replica of Elvis' corpse) cool;
2. The face presented to the mourners featured oddly arched eyebrows and a pug nose, even though Elvis had undergone plastic surgery (a nose job) to elongate his rather Indian-looking nose into a classical one for his movie career in Hollywood;
3. Elvis weighed approximately 250 pounds at the time of his "death", but his death certificate reduced this to a mere 170 pounds, in keeping with the appearance of the wax body
4.Elvis was a karate expert with an 8th degree black belt, so his hands were visibly calloused, whereas the body laid in the coffin had soft and pudgy, rather effeminate hands
5. One of the trademark Presley sideburns came off because the wax body was seen to be "sweating", i.e. melting, and a hairdresser later reported gluing it back on
6. Two hours after the public announcement of Elvis' death, a man who looked like a dead ringer for Elvis purchased a plane ticket for Buenos Aires under the name of John Burrows, an alias Elvis had used on several occasions, and one that was reported in government documents
7. A number of Elvis' most prized books such as his Bible, Chiro's Book of Numbers, and the Autobiography of a Yogi all disappeared after his alleged death, never to be recovered
8. On his last concert tour in the summer of 1977, Elvis regularly quipped that although he did not look his best right now, he would look good in his coffin
9. All photographs taken at the death scene have mysteriously disappeared, as have the toxicology reports;
10. Elvis' valuable jewellery and photographs of Priscilla Presley and Lisa Marie Presley were missing from Graceland.

Now, think what you want. But that seems to me like its enough information to believe that he is possibly still alive somewhere. If he is still alive, he would be 74 years of age.
