The police in Minneapolis has reportedly launched a murder probe into singer Prince's death.
Police are looking for doctors or "handlers" who treated the singer, as friends fear he may have been over-prescribed drugs, reports dailystar.co.uk.
"A crack team have been assigned with learning minute by minute what Prince was doing during his final days. But the investigation will also look into his activities over the last two years," a police source said.
As the "Purple rain" hitmaker's family gathered at his home for a memorial 24 hours after his private cremation, his brother-in-law told how the singer had not slept for six and a half days before he was found dead in a lift.
"I was with him just last weekend. He worked 154 hours straight. He was a good brother-in-law," Prince's brother-in-law Maurice Phillips said.
Prince was found dead at his home at Paisley Park in Chanhassen, Minnesota, on April 21.
