Father 'exterminated' children, grandchildren

A California man accused of killing nine of his children and grandchildren shook his head and wiped away tears as a prosecutor said in closing arguments he had exterminated his family.

Marcus Wesson, 58, is charged with fatally shooting seven of his children and two of his grandchildren at his home in Fresno in March 2004.

He fathered the victims with his legal wife and with daughters and nieces. Wesson is charged with rape, oral copulation, murder and continuous sexual abuse of a child.
