All wounds caused by 'long weapon'

Dr. H. Wayne Carver II, the Chief Medical Examiner of Connecticut, spoke at a press briefing Saturday about the scene he and his staff encountered at Sandy Hook Elementary as well as the state of the victims' bodies and the wounds they suffered.

"I have been at this for a third of a century," Carver said. "And my sensibilities may not be [that of] the average man, but this probably is the worst I have seen, or the worst that I know of any of my colleagues having seen."

Carver's team confirms the deaths were all caused by gunshot wounds, and the manner of death for all of the victims has been classified as homicide. Carver also said he and his team are close to completing all of the medical examinations, and they do have a list of all of the victims.

Above, Carver answers questions about the state of the bodies, the type of weapons used in the murders and whether the victims survived for long after being shot.
