Investigators are trying to figure out what led a bright but painfully awkward 20-year-old Adam Lanza to slaughter 26 children and adults at a Connecticut elementary school.
A medical examiner says the victims were killed by multiple rifle shots, some of them up close. Dr. H. Wayne Carver said at a news conference Saturday he believes ``everybody was hit more than once.''
Friday's massacre has elicited horror and soul-searching around the world.
Gov. Dannel P. Malloy says the ``innocent little boys and girls'' were ``taken from their families far too soon.''
Investigators have questioned the gunman's older brother, who's not believed to have been involved in the rampage at Sandy Hook Elementary in prosperous Newtown, 60 miles northeast of New York City.
One law enforcement official says they've haven't found a note or manifesto of Lanza the sort that sometimes turns up after murderous rampages.
Police say Lanza committed suicide after killing his mother and 26 others, most of them children.
Connecticut State Police also say the gunman forced his way into the building.
Lt. Paul Vance said Saturday morning that the suspect was not voluntarily let into Sandy Hook Elementary School in Newton.
Authorities say Lanza shot his mother on Friday, drove her car to Sandy Hook Elementary School in Newtown, and shot 20 children, six adults and himself.
Police, so far, have shed no light on a possible motive for the nation's second-deadliest school shooting.
Lanza was described by some as brilliant but remote. An official who spoke on condition of anonymity said it was not clear that Lanza had a job.
A law enforcement official who was briefed on the investigation says Lanza is believed to have suffered from a personality disorder and lived with his mother in a well-to-do part of prosperous Newtown, about 60 miles northeast of New York City.
Neighbors are doctors or hold white-collar positions. Lanza's parents filed for divorce in 2008.
