On August 16, 1977, Presley died aged 42 in the bathroom at Graceland. The official cause of death was cardiac arrhythmia, although toxicology reports strongly suggested that polypharmacy was the primary cause of death; "fourteen drugs were found in Elvis' system, with several drugs such as codeine in significant overprescribed quantities. Elvis Presley lay in repose in a 900-pound copper-lined coffin just inside the foyer while over 3,500 of Elvis' mourning fans passed by to pay their respects. A private funeral with 200 mourners was held on August 18, 1977 in the house, with the casket placed in front of the stained glass doorway of the music room. Graceland continued to be occupied by members of the family until the death of Elvis' aunt Delta in 1993, who had moved in at Elvis' invitation after her husband's death.
