Mark Stroman, 41, was pronounced dead late Wednesday from a lethal injection administered at a jail in Huntsville, Texas, a decade on from a shooting spree which left two people dead and seriously wounded a third victim, Rais Bhuiyan. "I am at peace," said Stroman in his final statement. "Hate is going on in this world and it has to stop. Hate causes a lifetime of pain.
