"Not a random act": Details emerge in attack on Nancy Pelosi's husband, Paul Pelosi

Paul Pelosi, the husband of House Speaker Nancy Pelosi, underwent surgery to repair a scull fracture after he was beaten with a hammer inside his San Francisco home Friday. Law enforcement sources told CBS News the intruder shouted "Where is Nancy?" and planned to detain Paul Pelosi until she got home. 

Police wouldn't comment on a motive, but said this was "not a random act," and that it was targeted and "wrong."

With the attacker in the house, police say Paul Pelosi was able to make an open-line 911 call around 2 a.m. Friday. The dispatcher could hear what sounded like someone being threatened in the background, and sent a high priority alert to law enforcement, according to federal sources.
