I noticed the same thing: the headline didn't match how I read the text. Since this is the Daily Mail, I was wondering if this use of "hacked to pieces" is some British thing, and I went to the article comments mainly to see if anyone wrote a comment on it (so far, I haven't seen any).
In florida...few yrs ago...amabulance call to a bar..”knife fight”....buddy of mine was there....responding...said there were 2 cubans laying there on their backs...feet almost touching....hands...arms...ears...various body parts all arround the bodies...he figures they stood face to face...and kept on chopping away...neither one ran...or even backed up....just chopped away till both fell dead.
