A football coach. An athletic director. And young, fresh-faced students.
They are among the 17 people killed by a gunman at Stoneman Douglas High School in Parkland, Florida, on Wednesday.
Broward County Sheriff Scott Israel said Thursday that all families who lost loved ones in the shooting have been notified. He said police will release a full list of the victims later in the day.
"Today is a day of healing, today is a day of mourning," Israel said.
Here are the victims who have been publicly identified so far:
Alyssa Alhadeff, soccer player
CNN spoke to a relative of Alyssa Alhadeff who said the family was notified Wednesday night that she had passed away.
Alyssa was a student at Stoneman Douglas and a soccer player for Parkland Travel Soccer.
"Alyssa Alhadeff was a loved and well respected member of our club and community," Parkland Travel Soccer said on Facebook. "Alyssa will be greatly missed."
The Facebook post also included a message from her family: "To Alyssa's Friends honor Alyssa by doing something fabulous in your life. Don't ever give up and inspire for greatness. Live for Alyssa! Be her voice and breathe for her. Alyssa loved you all forever!"
Alyssa also attended Camp Coleman, a Jewish sleepaway summer camp.
"On behalf of the entire Coleman community, we offer heartfelt condolences and prayers for comfort to Alyssa's family and friends. May Alyssa's memory forever be for a blessing," the camp said on Facebook.
Scott Beigel, teacher
Beigel, a geography teacher at Stoneman Douglas, was killed as he tried to usher students back into his classroom when the shooting broke out.
Kelsey Friend, one of Beigel's students, told CNN in an emotional interview that he was shot outside the classroom door and that he saved her life.
"Mr. Beigel was my hero and he still will forever be my hero. I will never forget the actions that he took for me and for fellow students in the classroom," Friend said. "I am alive today because of him."
She said the teacher was an amazing person and his memory would live on with her.
"If I could see him right now ... I'd give him a huge teddy bear to say thank you. But unfortunately, I can't do that," she said.
Beigel was also a counselor at Camp Starlight in Pennsylvania, which called him a "friend and hero" on Facebook.
Shooting victim Martin Duque, 14, was one of Isaac Briones' best friends.
"He was like, one of the nicest people I knew," said Briones, 15. "He was so caring."
Briones said he last saw Martin the day of the shooting during first period.
"We were just playing around, talking about jokes and stuff," said Isaac, who was outside the school Thursday with others holding a group of white balloons for the victims.
On Instagram, Miguel Duque wrote that words can't describe the pain of losing his brother. He added: "I love brother Martin you'll be missed buddy. I know you're in a better place. Duques forever man I love you junior!!! R.I.P Martin Duque!"
Dworet, a senior at Stoneman Douglas high school, was killed in the shooting, the University of Indianapolis confirmed. Dworet was recruited for the university swim team and would have been an incoming freshman this fall.
"Nick's death is a reminder that we are connected to the larger world, and when tragedy hits in places around the world, it oftentimes affects us at home," said Robert L. Manuel, University of Indianapolis president.
"Today, and in the coming days, I hope you will hold Nick, his family, all of the victims, as well as the Parkland community and first responders in your prayers."
Feis, the assistant football coach, was killed when he threw himself in front of students to protect them from oncoming bullets, according to football program spokeswoman Denis Lehtio. He suffered a gunshot wound and died after he was rushed into surgery, Lehtio said.
"He died the same way he lived -- he put himself second," she said. "He was a very kind soul, a very nice man. He died a hero."
Colton Haab, a 17-year-old junior who had a close relationship with Feis, told CNN he saw the coach running toward the sounds of gunshots.
"That's Coach Feis. He wants to make sure everybody is safe before himself," Haab said.
"(He) made sure everyone else's needs were met before his own. He was a hard worker. He worked after school, on the weekends, mowing lawns, just helping as many people as possible," Haab added.
Chad Lyons, a student and football player, said Feis was there for him when Lyons was going through leukemia treatments.
"He guided me through them. He would send me prayers. He would send me Bible scripts and just stuff to cheer up my day. Funny memes," Lyons said.
"He was just an amazing person to be led on and taught by, and I'm thankful enough to even be in his presence, just going through high school."
Guttenberg was among those who died in the school shooting, according to a Facebook post by her father, Fred.
"My heart is broken. Yesterday, Jennifer Bloom Guttenberg and I lost our baby girl to a violent shooting at her school. We lost our daughter and my son Jesse Guttenberg lost his sister.
"I am broken as I write this trying to figure out how my family gets through this. We appreciate all of the calls and messages and we apologize for not reacting to everyone individually," he added. "Hugs to all and hold your children tight."
Skidmore College, which Fred Guttenberg attended, released a statement saying their hearts go out to Jaime's parents and others affected by the tragedy.
"There really are no words to lessen the suffering that the families of victims are feeling at this moment, but perhaps knowing that we stand with them can provide some small measure of solace," the college said.
A married father of two and the athletic director at Marjory Stoneman Douglas High School, Chris Hixon wasn't shy about jumping in wherever he was needed, said friend and one-time colleague Dianne Sanzari.
Hixon, 49, belonged to a Roman Catholic church in Hollywood. The Archdiocese of Miami confirmed his death Thursday.
When a volleyball team needed a fill-in coach, Hixon took over; the same thing happened with the wrestling team, Sanzari said. And when the school needed someone to patrol the campus and monitor threats as a security specialist, Hixon did that, too.
It was in that security role that Hixon apparently came within range of the shooter.
Fifteen-year-old Luke Hoyer was a loving, sweet person who loved basketball and "smiled all the time," his aunt Joan Cox said.
"He was just a good kid ... very loving and just enjoyed life," said Cox, of Greenville, South Carolina.
She said Luke's parents, Gena and Tom Hoyer, searched for their son at hospitals before finally going to the law enforcement command center, where they eventually learned he had died.
"It's just a terrible thing," said Cox, who said the family — including Luke's older sister Abby and brother Jake — spent Christmas with her and other family in South Carolina. "We just all pretty much can't get over it."
Cara Loughran, 14, was an excellent student who loved the beach and her cousins, according to her family.
An aunt, Lindsay Fontana, wrote on Facebook: "I had to tell my 8-year-old daughters that their sweet cousin Cara was killed in the shooting at Stoneman Douglas High School yesterday. We are absolutely gutted."
"While your thoughts are appreciated, I beg you to DO SOMETHING," she wrote. "This should not have happened to our niece Cara and it cannot happen to other people's families."
Loughran's neighbor posted a picture of her cheering on a young boy riding a bike with training wheels.
"RIP Cara," Danny Vogel wrote, "and fly with the angels. You will be greatly missed, and we will always love you and celebrate your beautiful life."
Shooting victim Gina Montalto was a 14-year-old freshman who participated on the winter color guard squad at the school.
Friends and relatives posted tributes on Facebook, including mother Jennifer Montalto.
"She was a smart, loving, caring, and strong girl who brightened any room she entered. She will be missed by our family for all eternity," said the post.
One of Montalto's color guard instructors from middle school, Manuel Miranda, told the Miami Herald that Montalto was "the sweetest soul ever."
"She was kind, caring always smiling and wanting to help," Miranda said.
Joaquin Oliver, 17, was known by his nickname "Guac," short for "guacamole," because many couldn't pronounce his first name.
"My friend will literally never get to say, 'I graduated high school,'" said Tyra Hemans, a 19-year-old who said she had been friends with Oliver since they were freshmen.
Hemans said she last saw her friend at school the day of the shooting.
"It was just a brief 'Happy Valentine's,'" she said. "He was with his girlfriend and I was just like, 'Oh my God, you guys are so cute.'"
She added, "He's just a goofball. He's the only kid you'd know that would dye his hair bleach-blond, walk around school, put some tiger stripes in and just be unique. He was a unique soul."
Fourteen-year-old Alaina Petty was among those who died in the shooting, great-aunt Claudette McMahon Joshi confirmed in a Facebook post.
"There are no hashtags for moments like this, only sadness," she wrote, asking people to lift up Petty's family in prayer.
Petty attended a local Church of Jesus Christ of Latter-day Saints. Petty was a "valiant young member of the Coral Springs Ward," Church leader Stephen E. Thompson wrote in an update.
Meadow Pollack's parents called her phone repeatedly only to hear it ring, as they kept an anxious vigil outside the hospital. But on Thursday, her father, Andrew Pollack, confirmed that his daughter was among the dead, the Palm Beach Post reported.
Eighteen-year-old Pollack, a senior, had planned to attend Lynn University, her father said.
"Her life was taken way too soon and I have no words to describe how this feels," friend Gii Lovito posted on Facebook.
Family friend Adam Schachtel said in a Facebook post that "an angel was taken away from us in that horrific tragedy ... no words can be said so just prayers and sadness."
Helena Ramsey was soft-spoken, but also smart and a go-getter, her cousin Sefena Cooper said Thursday.
The 17-year-old junior especially loved hanging out with friends and family, "and for this to happen is heartbreaking," Cooper said.
"Although somewhat reserved, she had a relentless motivation towards her academic studies and her soft warm demeanor brought the best out in all who knew her," another relative, Curtis Page Jr., wrote on Facebook.
Trombone and baritone player Alex Schachter was a "sweetheart of a kid," according to a social media post by father Max Schachter.
In honor of his 14-year-old freshman son, Schachter wrote on a gofundme page that he was starting a scholarship fund "to help other students experience the joys of music as well as fund increased security at schools."
The message said: "Please help keep Alex's spirit alive."
Carmen Schentrup was a smart girl with a sweet smile.
In September, she was named one of 53 National Merit Scholarship Program semifinalists in the county and a classmate tweeted "we all praised for her intelligence."
Cousin Matt Brandow posted on Facebook that the 16-year-old visited Washington State recently and said she wanted to go to the University of Washington. He asked: you like the rain?
"She answers, I hate sweating in the humid Florida weather," Brandow wrote. "That's when I knew you were perfect for Washington."
Peter Wang, a 15-year-old ROTC student at Marjory Stoneman Douglas High School, wasn't interested in status but wanted to help others, relatives said.
A cousin, Aaron Chen, told the Miami Herald that Wang was last seen holding a door open so others could get away from the gunman.
Friends and relatives first thought Wang was just missing and checked with area hospitals. They later found out he had been killed.
"He wasn't supposed to die," Chen told First Coast News.
