No matter how long it's been since the one and only King passed away, his fans still continue to celebrate his life and the timeless music he shared with us.
While Presley fanatics obsess over every detail of his life, there are 7 bizarre secrets about Presley's death that still baffle us decades later.
1. His lost songs
Decades after he passed away, Elvis collectors are still buying his records and memorabilia, but it's unclear if there will ever be a complete set of the King's music.
While Presley obviously hasn't written any new music recently, new Elvis songs keep turning up, like when a recording cut from one of his movies was found in a New Jersey basement in 2003. Could there be even more records waiting to be discovered?
2. His final photograph
Lots of businesses were desperate to take advantage of the King's death, including the t-shirt sellers who sold souvenirs outside of Presley's open casket funeral. One of Presley's own family members, his cousin Billy Mann, earned a tidy sum snapping a candid shot of Elvis lying in his coffin.
He sold the photo to the National Enquirer for $18,000, and it made the front page of the paper's best-selling issue of all time. Presley's girlfriend, Ginger Alden, also tried to sell her story to the paper for as much as $100,000.
It turned out to be a smart move, because Presley didn't leave Alden anything in his will.
3. What killed the King?
Elvis went to the bathroom of his Graceland home in the middle of the night, and he was found there hours later by Ginger Alden. For weeks, that's all that was certain about the singer's death. The medical examiner ruled Presley died of cardiac arrhythmia, but there's no way to identify arrhythmia from a dead body.
It was later revealed that Presley's doctors were likely covering up their own responsibility, since they had provided Elvis with as many as 10,000 prescription pills the year he died. The combination of the 14 drugs in Presley's system when he died were probably what killed him.
But many of the King's biggest fans ask another question: is he really even dead?
