Here's a senseless tragedy that should never have happened.
But first, do you remember the Facebook Poke? It's still around, although people seem to be using it less and less. The feature lets you "poke" a friend. If they want they can "poke" you back. Nobody knows what it means - if anything at all. All it does is send you a notification that so-and-so has poked you.
But for one 29-year-old father of a young girl in Nottingham, England, a Poke meant his death. Richard Rovetto was in a taxi with his friend Scott Humphrey when they argued over a Poke Rovetto sent to Humphrey's girlfriend. Soon after, Humphrey repeatedly struck Rovetto who then hit his head on the concrete. He died hours later.
Now Humphrey will spend the next four years behind bars after being convicted of manslaughter. He says he's "genuinely remorseful," although Rovetto's family believe the sentence wasn't harsh enough.
