]>> The deafening sound of gunshots rang out as the day was coming to an end at this high school in Florida.>> Aah!
Now the suspected gunman, 19-year-old Nikolas Cruz, has been charged with 17 counts of premeditated murder. A dozen others were injured on Wednesday at Marjory Stoneman Douglas High School in Parkland, Florida.
Officials say Cruz, a former student at the high school about 45 miles north of Miami, was armed with an AR-15 style rifle. They say he had multiple ammunition magazines when he surrendered to officers in a nearby residential area, shown here in amateur video. Cruz had been expelled for unspecified disciplinary reasons and talked a lot about guns.
According to students that Reuters correspondent Bernie Woodall spoke with.>> Even the ones who just knew him a little bit knew that there was something a little off, and those words heard from quite a few people, something a little off about this guy. And unlike most of the school shooters of recent vintage in the United States, of which there have been quite a few, he did not kill himself or allow himself to be killed in a suicide by cop, if you will.
So it'll be a little different than some of the shootings, and they have a suspect to talk with.>> Cruz wore a gas mask as he stalked into the school, according to officials, who say he then pulled a fire alarm, prompting students and staff to pour into the hallways.
Then the carnage began. Cruz had recently moved in with another family after his mother's death in November according to a lawyer, who said he brought his AR-15 along with his other belongings. The family who had taken Cruz in said they thought he was depressed because of his mother's recent death, reportedly from complications from the flu.
The FBI is investigating whether Cruz left warning signs after a comment was made in 2017 on a Youtube video that read, I'm going to be a professional school shooter.>> We did our database checks. We could not positively identify him. We're going back, we're scrubbing the information, we're looking at it again.
But I'm not willing to say at this time that it was one and the same free person.>> Officials say they're working around the clock gathering evidence after the second most deadly shooting at a public school in US history.
