Well yeah anyone can say they accidentally overdosed. But only that person knows the truth. Honestly, how do you take 10, 15, 20 pills, whatever it takes to overdose accidentally?
The article, much like this thread is pure speculation. A man 47 is all that it said much less how many pills were taken. People have high or low tolerances toward medication, My wife can take 5000 mg of morphine, I can't handle anything more then aspirin so therefore his gardner for all we know can't hang with his sleeping disorder. This is nothing more then putting him back on the front page over he said, she said. Till he or someone else confirms, it's a black hole.
