Nikolas Cruz makes first court appearance since mass shooting

(CNN) — Nikolas Cruz made a brief appearance in court for a procedural matter Monday, shortly after a law enforcement source told CNN that the 19-year-old school shooter obtained 10 rifles in the last year or so.

Cruz purchased two weapons from Gun World of South Florida in Deerfield Beach, said Kim Waltuch, the store’s CEO. She would not provide details on the types of guns he purchased or on the time frame, but said the sales followed normal protocol for Florida firearms purchases.

As investigators work to track Cruz’s other gun purchases, students and staff at Marjory Stoneman Douglas High School say they’re determined to ensure that the deaths of their 17 classmates and teachers bring change. They’ve promised action in the wake of the massacre, and they’re headed to Tallahassee, Florida, to speak to legislators about school safety and gun control this week. They have school walkouts and a march scheduled in the coming weeks.

Some have gone on social media, vocal about what they experienced and what action they want to see from those in power. They’re demanding that state and federal lawmakers step up and do something.

They’re also coming for the National Rifle Association and any politician who takes money from the powerful gun lobby. The NRA did not return CNN’s call seeking comment.

“My message for the people in office is: You’re either with us or against us. We are losing our lives while the adults are playing around,” said junior Cameron Kasky, announcing a March 24 demonstration in Washington.

They plan to converge at the nation’s capital next month and have asked supporters who can’t make it to stage marches in their own communities, according to a mission statement for March For Our Lives.

In Washington on Monday, teen demonstrators lay on the ground in front of the White House to symbolize the 17 victims. Others carried flags and posters.

Parkland students are planning a trip to Tallahassee, during which they hope to have sit-downs with state legislators. About a hundred people, students and chaperones, are set to arrive at the Capitol on Wednesday.

How to help victims of the Florida school shooting

Marjory Stoneman Douglas High School remains closed through Wednesday, and officials say they hope to reopen the doors by week’s end. It’s not clear when students will return.

The school district has also proposed tearing down the building where the shooting happened, Parkland Mayor Christine Hunschofsky said.

Trump tweet angers students

Students who survived the shooting laid into President Donald Trump after he seemed to blame the FBI’s failure to follow up on a report about the school shooter on the agency’s attention and resources on the Russia investigation.

On Saturday, Trump tweeted, “Very sad that the FBI missed all of the many signals sent out by the Florida school shooter. This is not acceptable. They are spending too much time trying to prove Russian collusion with the Trump campaign – there is no collusion. Get back to the basics and make us all proud!”

The President’s tweet caused considerable outrage online, including among apparent survivors of the shooting. One wrote: “Oh my god. 17 OF MY CLASSMATES AND FRIENDS ARE GONE AND YOU HAVE THE AUDACITY TO MAKE THIS ABOUT RUSSIA???!! HAVE A DAMN HEART. You can keep all of your fake and meaningless ‘thoughts and prayers’.”

As the investigation continues, a review has been ordered by Attorney General Jeff Sessions into how a tip to the FBI about Cruz was missed and how the agency responds to indications of potential violence.

The FBI failed to act on a January 5 tip about “Cruz’s gun ownership, desire to kill people, erratic behavior and disturbing social media posts, as well as the potential of him conducting a school shooting,” the agency said.

The proper protocols weren’t followed and the FBI’s Miami office was not notified, the agency said.

A video blogger also said he warned the FBI in September about a possible school shooting threat from a YouTube user with the same name as Cruz. The FBI did not find information to identify the person, said Robert Lasky, FBI special agent in charge of the Miami division.

On Monday, a law enforcement source briefed on the investigation told CNN that Cruz had obtained at least 10 firearms, all of them rifles. Investigators are trying to track the purchases, which Cruz appears to have made in the past year or so, the source said.

Cruz, who is facing charges of premeditated murder, is willing to plead guilty to avoid the death penalty, according to the public defender’s office representing him.

He is being held without bond in Broward County and is scheduled to appear before a judge Monday afternoon for a hearing to address whether certain documents in the case should remain sealed. Judge Elizabeth Scherer seemed opposed to the defense motion during a morning hearing.

State Attorney Michael J. Satz said Saturday this “certainly is the type of case the death penalty was designed for,” but now is the time “to let the families grieve and bury their children and loved ones.”
