Darren Williams: Salon attack could have been prevented, report says
An attack on a woman gunned down in her hairdressing salon by her estranged husband could have been prevented by Gwent Police, a watchdog says.
Darren Williams, 45, was found hanged in wood hours after he shot and injured three women including estranged wife Rachel in Newport in August 2011.
Their son, Jack, 16, was found hanged in the same woodland six weeks later.
A separate review also found failings by police and children's services to safeguard the boy's welfare.
