Florida gunman Nikolas Cruz is willing to plead guilty to avoid the death penalty and spare the community from reliving the massacre in a trial, his public defender said.
Cruz, 19, faces charges of premeditated murder in Wednesday's shooting at Marjory Stoneman Douglas High School in Parkland, which left 17 people dead.
Broward County Public Defender Howard Finkelstein, who is representing the confessed gunman, said there's no question he killed the 14 students and three staff members.
"The only question is, does he live or does he die?" Finkelstein asked.
Prosecutors would need to agree not to ask for capital punishment and allow life without parole instead.
On Saturday, State Attorney Michael J. Satz said this "certainly is the type of case the death penalty was designed for," but that now is the time "to let the families grieve and bury their children and loved ones."
"Our office will announce our formal position at the appropriate time," Satz said.
Cruz's next court date is set for Monday morning. He is being held without bond following a video hearing Thursday in a Broward County court.
• In an emotional rally Saturday in Fort Lauderdale, politicians and Stoneman Douglas students called for a ban on assault weapons, and urged voters to kick out lawmakers who oppose the move or take money from the National Rifle Association.
• The school district has proposed tearing down the building where the shooting happened, Parkland Mayor Christine Hunschofsky said.
• President Donald Trump and the first lady visited injured patients at a Florida hospital.
• Five shooting victims remain in area hospitals. Broward Health North in Pompano Beach has one patient in critical condition and two patients in fair condition, and Broward Health Medical Center in Fort Lauderdale has two patients in fair condition, spokeswoman Jennifer Smith said.
• Math teacher Jim Gard says an administrator sent an email in late 2016, asking to be notified if Cruz came on campus with a backpack. The administrator
'Time for victims to be the change that we need'
Some Stoneman Douglas students joined a Democratic state lawmaker in an emotional rally Saturday afternoon in Fort Lauderdale, calling for a ban on assault weapons and asking voters to remove politicians who oppose such a move.
"If all our government and President can do is send thoughts and prayers, then it's time for victims to be the change that we need to see," student Emma Gonzalez, who survived Wednesday's shooting, said at the rally outside the federal courthouse.
"We certainly do not understand why it should be harder to make plans with friends on weekends than it is to buy an automatic or semiautomatic weapon."
The man who kicked off the rally, state Sen. Gary Farmer, called for legislation to ban assault weapons and high-volume magazines and establish a gun registry.
He said people calling for a focus on increasing school security are "missing the point," because even if security were strengthened, people with assault guns still could kill at parks and churches.
A crowd at times chanted, "Vote them out!" Some held signs such as "Vote Blue" and "Protect children, not guns."
Another Stoneman Douglas student, Cameron Kasky, encouraged the audience to identify and shame "anybody who is accepting money from the NRA."
"This is about the NRA and keeping them out of our politics and out of our schools," Kasky said.
President visits victims
The President also went to the Broward County Sheriff's Office headquarters, where he met with first responders who played a role in rescues and the arrest of the shooter.
"What a great job you've done, and we appreciate it very much," he said.
Trump told reporters at Broward Health North that he spoke to victims, and he applauded the efforts of the hospital staff and first responders to save lives.
When asked whether more gun laws were needed to prevent school shootings, he did not respond.
The shooting is at least the seventh at US middle and high schools this year, and has reignited a debate over gun control. Some blame congressional inaction for the massacre, while others say now is not the time for such political battles.
FBI says it failed to act on January tip
As the victims' loved ones mourn, more signs are emerging that authorities missed opportunities to intervene weeks before the massacre.
The FBI has acknowledged receiving two tips that appear to relate to Cruz ahead of the shooting. One was a January 5 call to a tip line from someone close to him -- one that the FBI said it failed to act on.
The caller provided information 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 information should have been assessed as a "potential threat to life," but the proper protocols weren't followed and the FBI's Miami office was not notified, the agency said.
FBI Director Christopher Wray said the bureau is investigating what happened.
"We have spoken with victims and families, and deeply regret the additional pain this causes all those affected by this horrific tragedy," Wray said in a statement.
The FBI's admission prompted Florida Gov. Rick Scott to call on Wray to resign
Also, a video blogger said he warned the FBI in September about a possible school shooting threat from aYouTube user with the same name as Cruz. An FBI agent confirmed a field officer in Jackson, Mississippi, received the tip and interviewed the person who shared it.
But no additional information was found to help identify the person who posted the comment and no connection was made to South Florida, said Robert Lasky, FBI special agent in charge of the Miami division.
Social media posts
Cruz's apparent digital footprint includes slurs against blacks and Muslims, and declarations of a desire to shoot people. Other social media posts show a photo of a rifle, a collection of firearms on a bed, and a photo taken through a scope looking out a window.
In a private Instagram group chat, Cruz talked about killing Mexicans, keeping black people in chains and cutting their necks. After one member expressed hatred for gay people, Cruz agreed, saying, "Shoot them in the back of head."
At one point in the chat, he wrote, "I think I am going to kill people." After a member told him not to say things like that, he said he was just playing.
In a public post on his Instagram page, Cruz showed what he called an "arsenal" on a bed -- seven guns and body armor. Another post on the page is a view down the barrel of a gun with a holographic sight out a window onto the street.
Cruz was staying with the family of someone he met at the high school after his adoptive parents died, said Jim Lewis, the host family's attorney.
The family knew he had a gun. "They had it locked up, and believed that that was going to be sufficient, that there wasn't going to be a problem," Lewis said.
The family was unaware of any mental illness beyond depression over his adoptive mother's recent death, the lawyer said.
But Gordon Weekes, executive chief assistant of Broward's public defender's office, said Thursday that Cruz is "suffering from significant mental illness and significant trauma."
Before his mother died, Broward sheriff's deputies were called to the Cruz family home 39 times since 2010, according to documents obtained by CNN.
The sheriff's office received a range of emergency calls that included reports of a mentally ill person, child/elderly abuse, a domestic disturbance and a missing person.
There were 20 calls for service over the past "few years" pertaining to Cruz, according to Broward County Sheriff Scott Israel.
