The latest on the tragedy in Tucson:
Authorities seeking the man seen above who is possibly associated with 22-year-old Jared Lee Loughner, the suspect in the tragic shooting Saturday morning that killed 6 people and injured 13, including Rep. Gabrielle Giffords. The man is described as a "person of interest" and was seen at the same location and at the same time.
Giffords was shot in the head and critically wounded in what authorities describe as a "targeted attempt on her life." Doctors at the University of Arizona Medical Center say she "is not in a medically-induced coma, but still under sedation from surgery."
Report: Loughner had become increasingly erratic in recent months: "Started to act oddly during his classes at Pima Community College, causing unease among other students. That behavior, along with a disturbing video, prompted school administrators to call in Mr. Loughner’s parents and tell them that their son had been suspended and would have to get a mental health evaluation to return to college."
Among those killed: 63-year-old John M. Roll, chief judge for the United States District Court for Arizona. Roll was appointed in 1991 by George H.W. Bush.
Other victims include: Gabriel Zimmerman, 30, who was the director of community outreach for Ms. Giffords. The others who died were identified as Christina Green, 9; Dorothy Morris, 76; Dorwin Stoddard, 76; and Phyllis Schneck, 79.
