Police are confirming that five people are injured after someone opened fire at an office complex in Phoenix on Wednesday. It is still unclear where the suspect is. Video footage from the scene showed at least one person taken out of the office on a gurney, but speaking at the scene, Sgt. Tommy Thompson said he could not yet say what happened. The shooting was mentioned at Wednesday's congressional hearing about gun violence by Rep. Gabrielle Giffords’s husband, Mark Kelly, who told the Senate panel there had just been a shooting.
