October 21, 1971 Elvis arrives at the Laboratory for the Patrica Parker Paternity suit

in August 1970, a woman named Patricia Ann Parker filed a paternity suit against Elvis in Los Angeles Superior Court. The 21-year-old waitress claimed she’d had a relationship with the King of Rock and Roll during his engagement in Las Vegas earlier that year, and she wanted $1,000 a month in support for the child she named Jason Peter Presley.

Parker’s only proof that she and Elvis were ever together was a black-and-white snapshot of the two of them taken in the corridor near his dressing room. Elvis gladly posed with anyone who wanted a picture, and he was appalled his generosity was being used against him in a court of law.
The judge decided the quickest way to arrive at the truth was to order blood tests to establish the baby’s paternity. The baby obviously needed to be tested, too, and in those days the blood was drawn from a small cut made in the child’s heel. Elvis and Parker were present for the procedure, and as the doctor made his incision, the child shrieked. Elvis reportedly clenched his jaw and cursed underneath his breath at Parker, who he felt had unnecessarily put her baby through great pain to undergo this fishing expedition.
The blood tests proved that the child was not Elvis’s.
