THE PARENTS: One of the parents who lost a child in the attack spoke publicly about his loss.
Robbie Parker fought back tears and struggled to catch his breath as he described his 6-year-old daughter, Emilie, as a little girl who loved to draw. He also reserved surprisingly kind words for the gunman, saying he was not mad and offering sympathy for the gunman's family.
To the man's family, he said, "I can't imagine how hard this experience must be for you."
THE GUNS: Federal authorities visited local gun ranges but found no evidence that the gunman trained for the attack or was an active member of the recreational gun community. Investigators also have interviewed gun dealers trying to determine whether there was any training or other behavior that precipitated the attack.
THE HISTORY: The Newtown massacre is the second-deadliest school shooting in U.S. history and one of the deadliest mass shootings around the world. A gunman at Virginia Tech University killed 33, including himself, in 2007. It appears that only Virginia Tech; the mass killings of 77 in Norway last year; and a resort massacre with 35 victims in Australia had greater death tolls across the world over the past 20 years.
