MINNEAPOLIS (AP) — The Latest on the investigation into Prince's death (all times local):

10 a.m.

A Minnesota doctor accused of illegally prescribing an opioid for Prince a week before the musician died has agreed to pay $30,000 to settle a federal civil claim.

The settlement comes as state prosecutors are planning to announce whether anyone will be charged in the two-year investigation into Prince's death.

Prince died on April 21, 2016, from an accidental overdose of fentanyl, a synthetic opioid. No one has been criminally charged.

But the federal government alleges that Dr. Michael Todd Schulenberg violated the Controlled Substances Act when he wrote a prescription in someone else's name on April 14, 2016.

The settlement released Thursday doesn't name Prince, but search warrants previously released say Schulenberg wrote a prescription for oxycodone in the name of Prince's bodyguard, intending it to go to Prince.

A two-year probe into the overdose death of music superstar Prince is reaching a critical stage as a county prosecutor reveals whether criminal charges will be filed.

Carver County Attorney Mark Metz planned a news conference Thursday morning to give an update on the investigation. It is scheduled for 11:30 a.m.

Prince died April 21, 2016, after being found alone and unresponsive in an elevator at his home and recording studio in a Minneapolis suburb. An autopsy showed he died of an accidental fentanyl overdose.
