The list of drinks is from a witness who was with him, never a reliable source, IME. If I'm interpreting the toxicology numbers correctly his BA was .21, which is high. That equates to roughly 5 drinks in his system when the sample was taken. For a male 1 drink = approximately .04, depending on weight. Basic math is you excrete .02 per hour, so over 6 hours of drinking your body has metabolized .12 (3 drinks) thus he had probably drunk at least 8 drinks. That's assuming the BA is from blood drawn when he was admitted to the hospital and not @ the autopsy. If the latter his body would have had 9 more hours to metabolize alcohol before he died (and a BA of .39 a the time of the incident - highly unlikely IMO.)
Since he wasn't planning to drive, no big deal, except being inebriated may have caused the stumble leading to the fatal fall.
