Oldest Murder Victim?

A 500,000 year old skull found in Spain may be the world's oldest murder victim. Whoever he (or she) was, he was killed by two blows to the front of the head, both of which cracked the skull.

Of course, we have absolutely no clue of the circumstances. The fact that the blows were to the front indicate this was probably a fight, not an execution or somebody sneaking up behind them with a sapper.

So, maybe it was a murder. It could also have been self defense.

Or, perhaps, the evidence of the world's first ever bar fight.
