Chaos as two arrested during Texas execution

Chaos erupted outside Texas' death chamber when the son of a condemned inmate became aggressive, shouted obscenities and threw fists after his father spoke his final words.

Billie Wayne Coble, a Vietnam War veteran who killed his estranged wife's parents and brother - and threatened to do the same to her in 1989, told the five witnesses he selected to attend his execution that he loved them.
