According to the report, Mac’s assistant found him unresponsive on his bed in a “praying position” — kneeling forward with his face resting on his knees. The assistant described him as already being “blue” during the 911 call.
There was a 1/4-inch abrasion on the bridge of his nose, and there was blood coming out of one nostril.
An empty bottle of alcohol was found on the nightstand, near Mac’s body … and a bottle of prescription pills was found in the bathroom. The list of pills recovered in the home include Xanax, oxycodone, hydrocodone, and generic Adderall.
Cops found a rolled-up $20 bill with white powdery residue in Mac’s right pocket — and an iPad in his home studio had “linear white powdery residue” on it. There were also 2 baggies found with the white powder.
We’re told the amount of each drug was not necessarily a lethal amount, but the combination is what killed him. Source
