The teen gunman accused of opening fire with a semi-automatic rifle at his former high school in Parkland, Florida, has been charged with 17 counts of premeditated murder, officials said Thursday.
Authorities said the suspect, identified as 19-year-old Nikolas Cruz, concealed himself in the crowd fleeing Marjory Stoneman Douglas High School following the massacre on Wednesday afternoon. He was arrested in nearby Coral Springs.
Fourteen others were wounded, five with life-threatening injuries, hospital officials said.
