CBS News reports:
An orphaned 19-year-old with a troubled past and an AR-15 rifle was charged with 17 counts of premeditated murder Thursday morning after being questioned for hours by state and federal authorities following the deadliest school shooting in the U.S. in five years. Fifteen wounded survivors were hospitalized as bodies were recovered from inside and around Marjory Stoneman Douglas High School.
Nikolas Jacob Cruz was booked into the Broward County Jail early Thursday, still wearing the hospital gown he was given after being treated for labored breathing following his arrest. Just before gunfire broke out, some students at the school thought they were having another fire drill. A law enforcement source said the suspect appears to have pulled the school fire alarm, causing chaos, then started shooting, reports CBS News news senior investigative producer Pat Milton.
