Video released today shows the husband of former U.S. House Speaker Nancy Pelosi fighting for control of a hammer with his assailant during a brutal attack in the couple's San Francisco home last year. The body-camera footage shows suspect David DePape wrest the tool from 82-year-old Paul Pelosi and lunge toward him the hammer over his head. The blow to Pelosi occurs out of view and the officers -- one of them cursing -- rush into the house and jump on DePape. Pelosi, apparently unconscious, can be seen lying face down on the floor. Alex has watched the bodycam footage and listened to the 911 call and will have audio to share -- including the attacker's interview by police.
