Florida teen charged with 17 murders legally bought AR-15

An orphaned 19-year-old with a troubled past and his own 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.

Fourteen wounded survivors were hospitalized as bodies were recovered from inside and around Marjory Stoneman Douglas High School.

Nikolas Cruz, still wearing a hospital gown after being treated for labored breathing, and weighing in at 5-foot-7 and 131 pounds, was ordered held without bond and booked into jail.

His former classmates thought they were having another drill Wednesday afternoon when a fire alarm sounded, requiring them to file out of their classrooms.

That’s when police say Cruz, equipped with a gas mask, smoke grenades and multiple magazines of ammunition, opened fire with a semi-automatic weapon, killing 17 people and sending hundreds of students fleeing into the streets.

It was the nation’s deadliest school shooting since a gunman attacked an elementary school in Newtown, Connecticut, more than five years ago. The overall death toll differs by how such shootings are defined, but Everytown For Gun Safety has tallied 290 school shootings in America since 2013, and this attack makes 18 so far this year.

Cruz purchased the AR-15 legally about a year ago, a law enforcement official who is familiar with the investigation told The Associated Press. The official, not authorized to discuss this publicly, spoke on condition of anonymity. Federal law allows people 18 and older to legally purchase long guns, including this kind of assault weapon.

President Donald Trump’s reaction focused on Cruz’s mental health.

“So many signs that the Florida shooter was mentally disturbed, even expelled from school for bad and erratic behavior. Neighbors and classmates knew he was a big problem. Must always report such instances to authorities, again and again!” Trump tweeted Thursday.

Authorities offered no immediate details about a possible motive, except to say that Cruz had been kicked out of the high school, which has about 3,000 students. Students who knew him described a volatile teenager whose strange behavior had caused others to end friendships with him.

Cruz’s mother Lynda Cruz died of pneumonia on Nov. 1 neighbors, friends and family members said, according to the Sun Sentinel . Cruz and her husband, who died of a heart attack several years ago, adopted Nikolas and his biological brother, Zachary, after the couple moved from Long Island in New York to Broward County.

The boys were left in the care of a family friend after their mother died, said family member Barbara Kumbatovich, of Long Island.

Unhappy there, Nikolas Cruz asked to move in with a friend’s family in northwest Broward. That family agreed and Cruz moved in around Thanksgiving. According to the family’s lawyer, who did not identify them, they knew that Cruz owned the AR-15 but made him keep it locked up in a cabinet. He did have the key, however.
