Some of the pills discovered at Prince's Paisley Park estate in Minnesota had prescriptions in the name of his friend and bodyguard. The Kornfelds' attorney, William Mauzy, has said Andrew had meant to give the medication to a doctor.
But there was a prescription for the opioid painkiller oxycodone written for Kirk Johnson, Prince's bodyguard.
Johnson has been working with Prince since the early 1980s. He admits to prescribing oxycodone to Prince on the day of the emergency on the plane "but put the prescription in Kirk Johnson's name for Prince's privacy".
On the same day that prescription was filled, Prince's private jet was forced to make an emergency landing in IL after the singer overdosed during a flight home after a concert in Atlanta.
-Cell tower data from Sprint, Verizon, AT&T and T-Mobile of all cell phones used at or near Prince's compound. He went to Paisley Park on April 21 - the day Prince was found - to drop off test results, he said.
Investigators are trying to figure out to what extant Johnson helped Prince hide his addiction.
"Dr. Schulenberg met with Prince and prescribed him Clonidine, Hydroxyzine Pamoate and Diazepam".
"Many of those areas where the pills were located would be places Prince would frequent, such as his bedroom and wardrobe/laundry room", one document said. The newly unsealed documents give the clearest picture yet of Prince's struggle with opioid painkillers.
According to one of the unsealed search warrants, investigators did not find fentanyl among the cache of pills, many of which were hidden in bottles labeled "Bayer" and "Alleve". And how long was he taking opioid pain medication?
Writing a prescription for someone under a different name is illegal, and Dr. Schulenberg could be stripped of his ability to prescribe controlled drugs.
It is illegal for a doctor to write a prescription for someone under another person's name.
Schulenberg's attorney, Amy Conners, disputed that. So far, no one has been charged.
"There are no restrictions on Dr. Schulenberg's medical license, and contrary to headlines and media reportspublished in the wake of today's unsealing of search warrants relating to the investigation, Dr. Schulenberg never directly prescribed opioids to Prince, nor did he ever prescribe opioids to any other person with the intent that they would be given to Prince", Conners said.
Dr. Michael Schulenberg was the star's physician.
Investigators have said little publicly about the case over the a year ago, other than it is active. Television station K-T-T-C reports that the search warrant executed April 21st, 2016, was available for public viewing for the first time Monday.
-All emails, images, google docs, etc.
Prince did not have a cellphone, and authorities searched multiple email accounts that belonged to him, as they tried to determine who he was communicating with and where he got the drugs that killed him, according to the search warrants.
No arrests have been made in connection with the ongoing investigation, which is being conducted by the Carver County Sheriff's Office and the Drug Enforcement Administration.
Singer Judith Hill, who was in a romantic relationship with Prince, was also interviewed.
While authorities have the power to ask a grand jury to investigate and issue subpoenas for testimony, that step hasn't been taken, the official said.
The documents state Prince didn't regularly see a doctor but got routine vitamin B12 injections so he could "feel better" before performing. Those appointments were typically set up by his manager.
Prince was 57 when he was found alone and unresponsive in an elevator at his Paisley Park home on April 21.
