The Dead Farmer and the Cow

The BBC reports that a 70 year old farmer has died in an "incident" with a cow.  It won't say what the incident was (and they don't say "accident" mind you).  No foul play is suspected, but they did kill the cow afterwards. 

Was this some sort of death from natural causes and the cow just happened to be standing there?  Did the cow do it?

I suppose we'll never know...
