The congresswoman was initially declared dead, she was shot point blank in the head, but it seems that in spite of having a bullet shoot all the way through her head she made it through surgery and was still responsive to doctors, though clearly in critical condition. A little girl who had been born on 9/11 was shot and killed.
At first people thought there were 12 shot, and half of them including the congresswoman was dead. In the end it was 19 shot, 6 dead, and her (and at least 5 others) in critical condition. There were people pretending to be dead, just to avoid getting shot. The guy was caught, thanks to some ballsy people who got the gun away from him while he supposedly reloading. Either way, it was just bystanders that stopped him.
The FBI is crawling all over the city, along with just about every other government agency imaginable.They're looking for a potential accomplice, who based on all reports is thought to be his father. A bomb was found in the woman's office several hours after she was shot. It probably would have been kept secret, but since there was a candlelight vigil going on there the bomb squad had to make people back off so they could trigger/disarm it.
