Officials confirm what many suspected.

A law enforcement official has confirmed that an opioid overdose is the cause of Prince’s death, The Guardian reports.

The official is close to the investigation, but has remained anonymous due to not being authorized to speak to the media. Now that an overdose has been confirmed, police are continuing to investigate whether a doctor was prescribing the drugs that led to his death.

Many suspected an overdose after stories of Prince’s longstanding addiction to painkillers came to light following his death. He did try to get help for his addiction, but died on the same day he was meeting with a specialist.

Last month, Prince’s sister confirmed an official memorial service will be held in August.
