Teen charged with three counts of murder in Ohio school shooting

Students and parents marched to the high school in Chardon, Ohio where three students were killed in a shooting on Monday. Thomas Lane Jr. has been charged with three juvenile counts of aggravated murder. NBC's Brian Williams reports.

CHARDON, Ohio -- A 17-year-old youth was charged Thursday with three juvenile counts of aggravated murder in shooting that killed three students at a high school.

Thomas "T.J." Lane was accused of pulling out a semiautomatic pistol he had stolen from his uncle and opening fire in the Chardon High School cafeteria on Monday. Three boys were fatally wounded, and two other students were injured. One is still in the hospital.

Lane also faces two counts of attempted aggravated murder and one count of felonious assault.

The juvenile counts of aggravated murder and attempted aggravated murder would mean only a few years in detention if Lane is convicted. But the prosecutor has already said he plans to try the boy as an adult. That could mean life in prison if he is found guilty.
