School is considered to be the children's "second home" and one of safest place for them, but after what happened to Sandy Hook Elementary School, parents, teachers and students can't seem to forget the most tragic incident of mass killing in their history.

What happened to Sandy Hook is the second-deadliest school shooting in U.S. history where 27 teachers and schoolchildren were killed (20 children from 5 to 10 years old and 7 adults). After the incident, parents are not so sure whether to send their children back to school or not.

Friday, December 14, 2012, gunman in Connecticut shooting rampage Adam Lanza carried enough ammunition to kill almost every children at  Sandy Hook Elementary school if he had enough time. The rifle used in the shootings was a .223-caliber Bushmaster, a semi-automatic civilian version of military's M16 and a model commonly seen at marksmanship competitions. "A Connecticut official said the gunman's mother was found dead in her pajamas in bed, shot four times in the head with a .22-caliber rifle. The killer then went to the school with guns he took from his mother, got inside by breaking a window and began blasting his way through the building." Adam Lanza shoot himself in the head just as he heard police drawing near to the classroom where he was slaughtering helpless children.

Investigators said that Adam Lanza went to Sandy Hook many years ago but they couldn't find any explanation why he went there Friday and committed this mass murder of helpless children and school staffs. Lanza had no criminal history, investigators also couldn't offer any explanation about Lanza's motive for shooting, not even letters or diaries that could shed light on it.


Jennifer Waters, who at 6 is the same age as many of the dead but attends another school, came to Mass at Saint Rose of Lima Roman Catholic church with lots of questions.

"The little children — are they with the angels?" she asked her mother. Joan Waters assured her daughter that they were.
