During a search warrant executed at Paisley Park on April 21, the day Prince was found dead, a suitcase was found in Prince's bedroom next to his bed.
They don't reveal answers, but do shed light on Prince's struggle with addiction to prescription opioids in the days before he died.
A Minnesota doctor is disputing that he ever prescribed opioids to Prince or to anyone else with the intent they be given to Prince.
It has been reported vitamin bottles were also found throughout Prince's home during the inspection.
Information in the warrants also revealed that investigators found a suitcase containing several prescription bottles in the name of Johnson, who told investigators previous year that the singer had been struggling with opiate use.
The prescription was dated April 14, 2016, the same day Prince was revived with an anti-overdose drug after falling ill on a plane.
A medical expert who predominantly treated Prince, named Doctor Michael Schulenberg, has reportedly admitted to prescribing the singer Oxycodone shortly before he reportedly overdosed on his private jet, which came nearly one week prior to his death.
Detectives also discovered Prince's suitcase - which was the one found with several narcotics inside (in prescription pill bottles under Johnson's name) - had the name tag of "Peter Bravestrong" - an alias name authorities believe Prince used when he traveled in an attempt to maintain his privacy.
The details from those documents show the possible direction of the criminal investigation into Prince's accidental overdose death nearly exactly a year ago, a death that left fans around the world heartbroken and bewildered.

The medical examiner's office said his death was the result of an accidental overdose of the opioid fentanyl, a synthetic drug 50 times more powerful than heroin. The agency's website on Monday listed no disciplinary or corrective actions taken against the doctor. In October 2016 it was termed "an active homicide investigation" in the documents, but no one has been criminally charged. They cite the complexity of tracking illegally obtained pills, the need to be sure before they issue subpoenas, and the high stakes for investigators and prosecutors, who don't want to suffer an embarrassing defeat in a high-profile trial.
Investigators have said little publicly about the case over the a year ago, other than it is active.
However, the medications were not prescribed to the musician under his own name.
Two Los Angeles attorneys say it happens all the time in Hollywood.
Prince's half-brother, Duane Nelson, said he used to get the drug for Prince to help him come down after shows, attorney Michael B. Padden said. He and five others were searching for Prince when Kornfeld said he heard a scream.
"They would be indicting every pharmacist in Beverly Hills if this were strictly enforced", Garofalo said Monday.
In practice, laws against prescribing drugs for someone under a false name are not usually enforced when a doctor intends to protect a celebrity's privacy, said Los Angeles attorney Ellyn Garofalo.
But, he says, that prescription is tangential to the case. If you would like to discuss another topic, look for a relevant article.
