Previously sealed court documents were opened Monday that describe the various drugs found in Prince‘s home after his death.

WHAT DRUGS WERE FOUND INSIDE PRINCE’S HOME?

The documents were not opened until this week because prosecutors did not want any potential witnesses to flee or evidence to be destroyed. Prescription pills in the name of the late singer’s friend and bodyguard were found in his home. However, the documents do not offer evidence about the source of the fentanyl that killed Prince on April 21 last year.

Medical examiners concluded that the singer died from an accidental overdose, and no one has been charged for the 57-year-old’s death. According to the autopsy report, Prince self-administered fentanyl, an opioid multiple times stronger than heroin.

The newly opened documents named a medication called Watson 853, the opioid painkiller also known as acetaminophen-hydrocodone. They are used to treat pain, rheumatoid arthritis, and coughs. There were also “numerous narcotic controlled substances,” some hidden in vitamin bottles.

Investigators were “made aware by witnesses that were interviewed that Prince recently had a history of going through withdrawals, which are believed to be the result of the abuse of prescriptions medication.”
