One of the 10 people killed in the Texas school shooting was a girl who had rejected the suspect's advances for months, and stood up to him a week ago in class, the victim's mother said.
Sadie Baze said her daughter, Shana Fisher, 16, was gunned down during art class at Santa Fe High School on Friday.
Police arrested the suspect, Dimitrios Pagourtzis, 17,who was also a student at the school in the southeastern Texas city of Santa Fe.
Baze said the suspect had pestered her daughter to go out with him for months. A week ago, her daughter stood up in class and told Pagourtzis that she wouldn't go out with him.
Before asking Shana out, the suspect had previously dated her best friend, Baze said, adding that's why she told her daughter to turn him down.
"One of the shotgun shells was for my daughter," Baze said. "She's never going to walk through the front door again."
Shana had turned 16 days earlier.
'I was frozen'
Pagourtzis used a shotgun and a revolver to shoot students and teachers, killing 10 people, police said. An additional 13 others were injured.
Deedra Van Ness' daughter, Isabelle Laymance,survived theshooting by hiding in a classroom closet. In a Facebook post Saturday titled "longest day of my life," she said her daughter told her the gunman was "yelling Woo Hoo!" as he fired in the classroom next door.
When her daughter first called to let her know about the shooting, she was whispering to avoid alerting the gunman.
"I was frozen, standing there with no idea what to do next," Van Ness posted.
The mother said she texted their friends and relatives to ask them not to call Isabelle to avoid giving away her hiding place.
The victims
One of the students killed was Jared Black, who turned 17 last week and was supposed to have a birthday party Saturday.
Other victims included Sabika Sheikh,a Pakistani exchange student; Chris Stone, 17; Angelique Ramirez; Christian Riley Garcia; Aaron Kyle McLeod; Kimberly Vaughan; Glenda Ann Perkins and Cynthia Tisdale, who were teachers.
The people hospitalized included retired Houston police Officer John Barnes, who served as a resource officer at the school and confronted the gunman.
Houston Police Chief Art Acevedo tweeted Friday that he had visited Barnes in the hospital, and he was "hanging in there."
Suspect is 'confused'
The alleged shooter used a shotgun and a .38 revolver legally owned by his father, Gov. Greg Abbott said.
The suspect's family issued a statement Saturday, saying they are shocked and confused, and expressing condolences to the victims. Pagourtzis is a "smart, quiet, sweet boy," they said.
"While we remain mostly in the dark about the specifics of yesterday's tragedy, what we have learned from media reports seems incompatible with the boy we love," they said.
The family said they are cooperating with investigators and will make no other public comments until the fact-finding stage is completed.
Pagourtzis is being held without bail and is accused of capital murder of multiple people and aggravated assault on a public servant. He has not entered a plea.
Attorneys Robert Barfield and Nicholas Poehl said they had met with Pagourtzis for two, 30-minute visits. Barfield said his client is "not doing well" and is "confused."
"I think that at this point, I think he's in some kind of shock," Poehl told CNN on Sunday. "It's going to be a while before I can tell you more."
The suspect won't face the death penalty if he is convicted. Under Texas law, offenders who are under age 18 and charged with a capital offense face a maximum punishment of life in prison with the possibility of parole after 40 years, according to Robert Dunham of the Death Penalty Information Center.
The suspect told an investigator he acted alone and spared people he liked because he wanted his story told, according to a probable cause affidavit.
Gunman acted alone
Gunfire started not long after classes began around 7:30 a.m. (8:30 a.m. ET), officials said.
Two school resource officers were on the campus and confronted the shooter, Abbott said.
Authorities later found explosive devices -- including pipe bombs and pressure cookers -- in and near the school, a law enforcement official said.
Galveston County Judge Mark Henry told reporters that the suspect had devices but none were functional. One was a pressure cooker with an alarm clock and nails, but no explosive material. Authorities also found an unlit Molotov cocktail, he said.
Investigators believe Pagourtzis acted alone, a law enforcement official told CNN on Saturday.
'We will grieve together'
This is the 22nd US school shooting so far this year, and the third instance in eight days in which a gunman was on a school campus.
President Donald Trump addressed the school shooting, saying that mass shootings have been "going on too long." He said federal authorities are coordinating with local officials.
The Santa Fe school district will close its schools Monday and Tuesday, officials said -- but students and staff are slowly being allowed to collect their belongings from part of the high school.
The community of Santa Fe is in mourning, its congressman said, and residents "will pull together" like they did after Hurricane Harvey months ago.
"We will grieve together, we will love one another, we will work together. We did it after Harvey -- still doing it after Harvey," US Rep. Randy Weber told reporters Saturday, referring to the storm thatravaged the Houston area in August. "We'll do it after this."
"We will get through this," he said.
