Gov. Butch Otter ordered flags at the Idaho Capitol and other state buildings to be flown at half-staff until Tuesday, following a similar order from President Obama given out of respect for victims of a mass shooting at a Connecticut elementary school.  Otter made the announcement just hours after at least 20 children and eight adults were killed in the brutal rampage in Newtown.  Adam Lanza is believed to have shot himself after killing the others.  Law enforcement officials say the 20-year-old Lanza killed his mother, a teacher at Sandy Hook Elementary, then drove to the school where he targeted young children.  It’s America's second-deadliest school shooting, surpassed only by the Virginia Tech massacre that left 33 people dead in 2007.
