A shooting at a Connecticut school has left 27 people dead, including 20 elementary school children. They were shot and killed at a Newtown, Conn., elementary school Friday morning.
The gunman was found dead at the scene. It is believed that the gunman's mother was a teacher at the school. She is believed to be one of the people who was killed.
The shooting erupted at Sandy Hook Elementary School at 9:41 a.m. Eastern time, prompting the town of Newtown to lock down all of its schools and draw SWAT teams to the school.
A law enforcement official said that a gun used in the attacks is a .223-caliber rifle. ABC News reports the gunman had a total of four weapons and was wearing a bulletproof vest. The official also said that New Jersey state police are searching a location in the state in connection with the shootings.
The school has kindergarten through 4th grade classes.
The shooting comes just three days after masked gunman Jacob Roberts opened fire in a busy Portland, Ore., mall killing two before turning the gun on himself.
Today's shooting occurred at the Sandy Hook Elementary School in Newtown, about 12 miles east of Danbury.
State Police received the first 911 call at 9:41a.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.
While some students have been reunited with their parents on the school's perimeter, one group of students remains unaccounted for, according to a source with a child in the school.
Three patients have been taken to Danbury Hospital, which is also on lockdown, according to the hospital's Facebook page.
"Out of abundance of caution and not because of any direct threat Danbury Hospital is under lockdown," the statement said. "This allows us simply to focus on the important work at hand."
Newtown Public School District secretary of superintendent Kathy June said in a statement that the district's school were locked down because of the report of a shooting. "The district is taking preventive measures by putting all schools in lockdown until we ensure the safety of all students and staff."
