US police searching for 70-year-old gunman after Arizona office shooting The gunfire at the office complex prompted workers to lock the doors to their offices and hide far from the windows. "Everyone was just scared, honestly, just scared," said Navika Sood, assistant director of nursing at First at Home Health Services who along with her co-workers locked the entrances to their office. America's latest public shooting came on the same day Congress took up the issue of gun control for the first time since the Connecticut school shooting in December left 20 young children dead and changed the national conversation on guns. Former Arizona Rep. Gabrielle Giffords who was shot in the head during a 2011 shooting rampage in Tucson that left 6 people dead appeared in Washington to testify in favor of stricter gun controls.
