Opioid painkillers were found hidden throughout Prince's Paisley Park estate in the days after his death in April 2016, new court documents released by the Minnesota Judicial Branch reveal.
Schulenberg's attorney, Amy Conners, confirmed that her client hasn't had any more requests from authorities.
When authorities later checked a database set up to monitor who's getting prescriptions for controlled substances, they found nothing for Prince.
A search warrant filed in the investigation of pop superstar Prince's death says the singer routinely got vitamin B12 injections so he could "feel better" before performances. Authorities haven't yet charged anyone in the case.
An online search reveals a multitude of sources that say that capsule is a mixture of acetaminophen and hydrocodone, a prescription classified as a narcotic.
Almost everyone who was close to Prince - and who has been willing to speak to the media - said they never saw him taking any drugs. A day before Prince's death, on April 20, Johnson picked up the prescriptions under his name; he told county investigators that "this was the first time he had ever done something like that for Prince".
Joe Tamburino is not associated with the Prince case.
It is illegal for a doctor to write a prescription for someone under another person's name.
Some pill bottles had Prince's long-time friend and estate manager Kirk Johnson's name on them.
Federal prosecutors and the Drug Enforcement Administration are investigating how Prince obtained prescription medications and from whom. His autopsy revealed an overdose of fentanyl, a drug 50 times more powerful than heroin.
None of the medications found in Prince's home following his death previous year were prescribed to him, according to court documents unsealed Monday.
The legal papers also suggest that Prince was battling with prescription opioid addiction. Investigators learned "that Prince Rogers Nelson had no prescriptions issued to him and that Kirk Johnson had only one, Oxycodone which was prescribed on 04-14-16 by Dr. Michael Schulenberg, the same doctor who was at the scene of Paisley Park on 04-21-16when deputies arrived and the same doctor who admitted in a statement to Detective Chris Nelson that he had prescribed Prince a prescription for oxycodone the same day as the emergency plane landing but put the prescription in Kirk Johnson's name for Prince's privacy".
Messages left with attorneys for Schulenberg and Johnson weren't immediately returned Monday.
Johnson's attorney, Clayton Tyler, said Johnson "did not secure nor supply the drugs which caused Prince's death". Almost a year after Prince died from an accidental drug overdose in his suburban Minneapolis. They still don't know the origin of those drugs and there has been no indication that they are poised to hold anyone responsible anytime soon.
Authorities said Prince's laptop was not taken during an initial warrant but it became clear later in the investigation that items on it would be significant when they discovered he did not communicate by cellphone, but instead used email and the hard phone line at Paisley Park extensively.
