LONDON (AP) — The family of an American slain in last week's terror attack in London expressed gratitude for the kindness of strangers on Monday, offering hope and resolve that some good would result from the tragedy. Kurt W. Cochran, 54, of Utah, was on the last day of a European trip celebrating his 25th wedding anniversary when a man in an SUV mowed down pedestrians on Westminster Bridge, then fatally stabbed a police officer on the grounds of Parliament. For the last decade, Cochran and his wife ran a recording studio in their basement where friends say he helped musicians develop their talents. The next day, a dozen members of Cochran's family gathered to face the media at London police headquarters, sharing their shock and sense of loss. The family offered profuse thanks — to first responders, to British and American authorities, to Delta airlines for arranging travel to London, and to people who had sent notes, prayer and donations since Wednesday's attack.
