Remembering the victims:
Tonight's AC360 focused first on the victims and then on the apparent mental illness of the shooter. Both the 8:00 and 10:00 PM hours were anchored live with similar segments in both hours. Guests included Deb Feyerick, Gary Tuchman, Mary Ellen O'Toole, John King, Drew Griffin, Fran Townsend, Shawn Henry, Benita Bell, Joe Johns and Terrie Durham.
Kyung Lah again reported on the flooding in Colorado at the end of the program.
