Following the release of Prince's toxicology results, which shows that he died from an accidental overdose of Fentanyl, a criminal investigation is now underway over how the late guitarist obtained the powerful opioid that ultimately killed him.

TMZ also revealed Prince’s death certificate, which outlines his official time of death as 10:07AM on April 21. However, the details on the death certificate bear some discrepancies. 10:07AM is the time he was pronounced dead when paramedics arrived at his Paisley Park estate. He may have passed from the overdose hours before paramedics finally arrived.

Fentanyl is a synthetic opioid that is 100 times more powerful than morphine which makes this story more complicated than a painkiller overdose. The drug can be administered by injection, lozenge or patch to treat severe pain after surgery and to manage chronic pain. However, it’s commonly sold illegally and misused by addicts.

Although difficult to process, Prince was suffering from a drug addiction and in the process of getting help. Whether Fentanyl had been prescribed to Prince is unclear; but its extreme potency is usually prescribed to patients who have become tolerant of other opioids for pain relief. Sources close to the investigation, admit to knowing "for a long time" that Fentanyl was the cause of The Purple One’s death.

Prince was 5'3" and weighed 112 pounds at his time of death and reportedly had surgery several years ago on an ailing hip. He was quite possibly treating the pain from his surgery and simultaneously battling his addiction to the drug. If someone illegally prescribes or fills a Fentanyl prescription for a patient who dies as a result, they could face third degree murder charges and up to 25 years in prison.

The day before Prince was found dead, he was treated by Dr. Michael Todd Schulenberg for withdrawal symptoms from opioid addiction. The physician treated Prince for fatigue, anemia and concerns about opiate withdrawal.
