Some disturbing details on the days leading up to the Sandy Hook school massacre.  Reports, unveiled on Monday, indicate the gunman--Adam Lanza--made online threats in the days leading up to the tragedy almost a year ago.  The mother of a boy who was chatting online with Lanza said he told him of another school shooting coming soon.  The mother reported that conversation to Hartford officials but apparently too late to stop the shooting that killed 20 young children.  The report also found Lanza with a preoccupation with mass murder--particularly the Columbine school shooting.  Still, though, no definitive word on a motive for that attack.  Unfortunately, the boy and his mother did everything right in reporting what they had heard to authorities.  It wasn't in time, though, to save the victims. Another indication, that any threat needs to be taken seriously.  Better to be safe than sorry.
