Investigators are looking into the possibility that a drug overdose may have caused the death of music legend Prince last week.

Officials are also investigating if drugs were prescribed to the singer in the weeks preceding his death and whether a doctor was aboard the plane that made an emergency landing following a concert in Atlanta less than a week before Prince died.

According to officials Prince received an injection of Narcan, which is commonly used in suspected opioid overdoses, while the plane was on the runway in Moline, IL.

Chief Deputy Jason Kamerud of the Carver County Sheriff's Department would not make any specific comments on the direction of the investigation but told E! News, "We're continuing to investigate the circumstances of Prince's death. The ME will provide toxicology results with her findings. I expect it to be a few weeks before we have her report(s)."

Sheriff Jim Olson said in a press conference that there were no signs of trauma and suicide is not believed to be the cause of death.
