A Minnesota doctor, who prescribed medicine to Prince and was at his Paisley Park home the day he died, has disappeared from his medical center, a new report claims.

Dr. Michael Todd Schulenberg is mentioned in the search warrant as part of the investigation into Prince’s death, according to TMZ. Police reportedly obtained a search warrant for the North Memorial Medical Center where Schulenberg allegedly worked, but whose name has since reportedly “disappeared from the roster” for reasons unknown.

In the warrant it reportedly asks for all “medical records, documents, reports, charts, photos, prescriptions, doctor’s notes, and medical notes” for the patient Prince Rogers Nelson.

The Minnesota doctor was allegedly interviewed, and reportedly admitted to treating the legendary singer two times in April, once the day before he died. Schulenberg allegedly explained to police that he was at the singers home to drop off test results from that appointment.

The warrant reportedly mentions the plane trip the week before the singer died. As previously reported, Prince had to make an emergency landing where he was rushed to the hospital. Reports say the singer had to be carried off the plane. He was transported to a local hospital by ambulance and released three hours later.
