Fentanyl is a respiratory depressant. It kills you by stopping your breathing.

More than likely with the stress of the moron cops knee on his back/neck, cardiomegaly (enlarged heart), adrenaline of the situation, his heart gave out.

Compromised heart function = compromised oxygen exchange/air hunger.

Someone ODing would slip into a coma and stop breathing.
