No, I didn't miss the fact the father of the child called him "drunken".  But that doesn't mean he actually was drunk.   

But this behavior goes far beyond most drunks. Unless you think it's typical drunk behavior to kidnap a child and call him the devil while trying to kill him.  He may very well have been under the influence of some other substance, in addition to, or instead of, alcohol.  Or he may actually be mentally ill.
