MINNEAPOLIS (AP) — The Latest on the investigation into the death of Prince (all times local):
5 p.m.
A law enforcement official says investigators looking into Prince's death are seeking to identify every doctor and pharmacy that may have supplied the singer prescription drugs, including online sources.
The official told The Associated Press on Wednesday that the search for Internet suppliers involves examining computer drives from Prince's Minnesota home, where he was found dead on April 21.
The official has been briefed on the investigation and spoke on condition of anonymity because the person wasn't authorized to speak to the media.
The official says investigators want to determine whether any doctor broke the law by overprescribing drugs or prescribing drugs without first giving Prince a requisite physical.
At least two doctors have been identified as having contact with Prince or his staff before he died. Neither is accused of wrongdoing.

A Minnesota physician questioned by investigators in Prince's death is an experienced family care physician who until recently worked for a Twin Cities health care system.
A search warrant revealed Tuesday that Dr. Michael Todd Schulenberg treated Prince on April 7 and April 20 and prescribed him medications, though it didn't specify which or say whether Prince took them. Prince was found dead April 21 in his suburban Minneapolis home.
Schulenberg was a primary care physician for North Memorial Medical Center, but he has since left the job. A spokeswoman for the health care system declined to elaborate.
Schulenberg earned his MBA in health care recently from the University of St. Thomas in St. Paul. In a 2012 YouTube video posted by the university, Schulenberg said he was then part of the "leadership group" at Ridgeview Medical Center in Carver County.

A search warrant reveals that a Minnesota doctor saw Prince twice in the month before his death — including the day before he died — and prescribed him medication.
The warrant says Dr. Michael Todd Schulenberg treated Prince on April 7 and April 20. The warrant was obtained by at least two news outlets before authorities moved to ensure it was sealed.
The warrant did not specify what medications were prescribed or whether Prince took them.
The warrant was carried out last Thursday at North Memorial Medical Center in the Minneapolis suburb of Robbinsdale.
A spokeswoman for North Memorial Medical Center said Schulenberg was a primary care physician at its Minnetonka clinic but that he no longer works for the health care system. No one answered the door at the doctor's home on Tuesday and phone messages left for him weren't returned.
