Benjamin was laid to rest at Graceland’s Meditation Garden, where his famous grandfather Elvis Presley was also buried.
Graceland was Lisa Marie's personal playground growing up.
She once shared, "I have a really strong sense of home here. I always really happy when I'm here. It's basically a time capsule."
On Thursday, TMZ reported that Presley suffered “full” cardiac arrest at home in Calabasas, California.
A source told the outlet that epinephrine was administered to Presley to help her regain her pulse. She was then rushed to a hospital in West Hills, where she later died.
Lisa Marie’s mom Priscilla announced the sad news in a statement to People. She said, “It is with a heavy heart that I must share the devastating news that my beautiful daughter Lisa Marie has left us. She was the most passionate, strong, and loving woman I have ever known. We ask for privacy as we try to deal with this profound loss. Thank you for the love and prayers. At this time, there will be no further comment."
