April 17 (UPI) -- Rock star Prince was in possession of prescription medicine labeled with his name and an alias at the time of his death, search warrants unsealed Monday said.
The warrant affadvits say six people were present in the home when investigators arrived. Among them Andrew Kornfeld, who said he was there to assess Prince for a drug dependency program administered by his father, Dr. Howard Kornfeld. Andrew Kornfeld said he brought controlled substances with him, but did not administer them. The affadavits also say Dr. Todd Michael Schulenberg told detectives he issued two prescriptions for oxycodone, under Johnson's name to protect Prince's privacy. They add that fentanyl was never prescribed to Prince, and that several types of painkilling medication was found in the house.
Also mentioned in the 11 warrants, executed between April 21 and Sept. 19, were Prince's practice of traveling under an assumed name, Peter Bravestrong, and that Prince would receive regular injections of vitamin B12 prior to performances.
An ongoing state and federal criminal investigation of Prince's death has concentrated on his use of painkillers and how he acquired them.
