The Federal Drug Enforcement Administration is now looking into Prince's death, giving off the impression that doctors were perhaps over-prescribing medications to the singer, making them enablers.

TMZ said drugs are the focal point of the investigation, and the DEA and the Minnesota Attorney General are "looking into the various prescriptions that were written for Prince, and the focus is opiates."

Authorities believe that opiates will likely be either the sole or at least a significant factor in his death, the celebrity website said.

Aside from doctors who are able to write prescriptions, pharmacies are also being investigated. In fact, a search warrant was executed at one of Prince's local pharmacies on April 29. Basically, authorities want to know who, if anyone, was enabling Prince to take medication. TMZ has said that Prince overdosed on Percocet just a few days prior to his death.

The DEA's involvement comes as news was reported that Prince's team had contacted a California addiction doctor, as they apparently felt he needed professional help, especially considering the reported overdose.

Prince was believed to have signed off on getting help.

However, the doctor who was called, Dr. Howard Kornfeld, didn't meet with Prince, nor did his son, Andrew Kornfeld, a specialist with Recovery Without Walls. Andrew, however, had flown to Minnesota and arrived at Prince's home just after he was found dead in an elevator. Andrew, his attorney said, was the one who called 911.

The lawyer just said Andrew did not supply Prince with any drugs, although he did have synthetic opiates in his backpack. The drug is called buprenorphine, a synthetic opiate for pain management and to wean people off actual opiates.

How bad Prince's alleged addiction was isn't exactly known, but he was a familiar face at his area Walgreens, a place he made four runs to in the week that he died.

In the week after his death, many credible media outlets have floated the idea that Prince died on April 21 perhaps from an overdose.

TMZ, who broke the news of Prince's death, said on April 29 that the iconic singer was able to get his supply of prescription drugs from more than one doctor, and at least one of them was a "personal friend."

If he was addicted to prescription painkillers, as some believe, it's all too likely that he doctor shopped and had more than one medical professional prescribing him pills. Percocet and similar painkillers are a controlled substance, and a single doctor who prescribes an excessive number of pills will be flagged by state and federal authorities.
