Prince's death has been largely a mystery since he was found unresponsive in an elevator at his Paisley Park estate.
But according to an affidavit from the local sheriff's office, a Minnesota doctor saw Prince twice in the weeks before he died and showed up at the musician's house to drop off test results just as he was pronounced dead.
The doctor, Michael T. Schulenberg, saw Prince on April 7 and April 20 — the day before Prince died — but the affidavit does not disclose what Dr. Schulenberg was treating Prince for, what he prescribed or whether Prince actually took anything prescribed by the doctor.
As part of a search warrant, investigators searched Prince's estate Tuesday but were quiet on why they were revisiting the scene. They tweeted, "Detectives are revisiting the scene at Paisley Park as a component of a complete investigation."
There are a lot of theories surrounding Prince's untimely death, but real answers could be weeks away as the music icon's autopsy results are still pending.
