Drunk at 8:30 in the morning?...or, still drunk?
My guess would be the woman was drinking within a few hours of the incident.
Sheen, recovering from last night, awoke, may have confronted her about her morning drinks, made the lush wife go nuts. May have tried to take a bottle from her. Hollywood smarts not to mention that to police, because that goes into report, then to the public, triggers embarrassment and child welfare visits.
Just a guess at what happened.
Good night and Merry Christmas!!
