(ABC NEWS/AP) -- Authorities have released the names of the 26 people gunned down in a rampage at a Connecticut elementary school.
A medical examiner says all the victims of the Connecticut school shooting were killed up close by multiple rifle shots. All six adults killed at the school were women. Of the 20 children who were shot to death, eight were boys and 12 were girls. All the children were ages 6 or 7.

Dr. H. Wayne Carver said at a news conference Saturday the deaths are classified as homicides. He says he believes "everybody was hit more than once."
Lt. Paul Vance said Saturday morning that the suspect was not voluntarily let into Sandy Hook Elementary School in Newton.
Authorities say 20-year-old Adam Lanza shot his mother on Friday, drove her car to Sandy Hook Elementary School in Newtown, and shot 20 children, six adults and himself.

The first official said Adam Lanza's older brother, 24-year-old Ryan, of Hoboken, N.J., was questioned by police. An earlier report from a law enforcement official mistakenly transposed the brothers' first names. Police say Ryan is not under any suspicion.
Sources said the shooter was armed with a Glock semi automatic handgun and a Sig Sauer semi automatic handgun, law enforcement sources told ABC News. Additionally, .223 caliber shell casings--a rifle caliber--were also found at the scene. He was wearing a bullet-proof vest when he opened fire in the elementary school
First grade teacher Kaitlin Roig, 29, locked her 14 students in a class bathroom and listened to "tons of shooting" until police came to help.
"It was horrific," Roig said. "I thought we were going to die."
She said that the terrified kids were saying, "I just want Christmas…I don't want to die. I just want to have Christmas."
A tearful President Obama said there's "not a parent in America who doesn't feel the overwhelming grief that I do."
The president had to pause to compose himself after saying these were "beautiful little kids between the ages of 5 and 10." As he continued with his statement, Obama wiped away tears from each eye.

It is the second worst mass shooting in U.S. history, exceeded only by the Virginia Tech shooting in 2007 when 32 were killed before the shooter turned the gun on himself. The carnage exceeds the 1999 Columbine High School shooting in which 13 died and 24 were injured.
The Newtown shooting comes three days after masked gunman Jacob Roberts opened fire in a busy Oregon mall, killing two before turning the gun on himself.
State Police received the first 911 call at 9:41 a.m. and immediately began sending emergency units from the western part of the state. Initial 911 calls stated that multiple students were trapped in a classroom, possibly with a gunman, according to a Connecticut State Police source
