Pop icon Prince might have been dead for at least six hours before his body was found in an elevator at his

Paisley Park

estate in Minnesota, a new report suggested.

It is reported that a paramedic who responded to the 911 emergency call told staff members, law enforcement officers and others that the '

Purple Rain

' singer may have been dead for more than six hours, reported Us magazine.

Prince autopsy completed: singer reportedly overdosed days before death

Prince was found with prescription painkillers in his home when he died, and had been battling a decade-old addiction to opioids. Sources said that the singer had in fact become 'increasingly agitated' in the days following an overdose that prompted his plane to make an emergency landing on April 15.

In an attempt to remedy the situation, a staff member at Paisley Park called someone in

New York

in the early hours of April 20 seeking advice on how to calm Prince down.
