The man who killed three women after a stand-off at a veterans’ home in Napa Valley, California was a former patient, authorities say. The three victims were all employees at the centre in Yountville. The residential centre provides mental health services for veterans of the wars in Iraq and Afghanistan. The suspected gunman, who died at the scene, has been named as Albert Wong, 36. No motive for the attack has been identified, police say. Wong, reportedly a former US Army rifleman, had left a programme to treat post-traumatic stress disorder (PTSD). The gunman entered the building while employees were having cake as a leaving celebration for some colleagues. After a siege lasting all day police discovered the four bodies in a room at The Pathway Home on Friday evening.
