New documents released by Minnesota's Carver County Sheriff's Office suggest that Prince may have been addicted to cocaine in 2011.

Details of a five-year old 911 call made by an unidentified woman from Germany claim that Prince had an "uncontrollable cocaine habit". The call log was released by the sheriff's office along with details of other calls made in relation to the singer's Paisley Park home since 2011.

The report further suggests that authorities thought that the call was a "bit murky" and since the singer was not "in immediate danger" they "would not be able to do anything about it".

Whether or not the call had any truth behind it is debatable as the identity of the woman is not known nor was her relationship with the late singer established. However, this was not the only call that reportedly provided unknown information about Prince. Another call made on 21 April – the day Prince died – claimed that the singer had a 17-year-old son, who wanted to attend his funeral.

While most of Prince's acquaintances claim that the Purple Rain singer was never seen doing drugs, reports have surfaced suggesting that he may have been addicted to painkillers. A report in TMZ mentioned family members claiming that Prince had developed an addiction to painkillers after undergoing a hip surgery. Moreover, during investigations authorities found opioid medication at his Minnesota home, according to a CNN report.

Prince died at the age of 57 at his Paisley Park residence on 21 April, while an autopsy report is yet to be furnished, the reason behind his death remains a mystery.
