They had more ahead of them than behind, the 10 young people who lost their lives in the Astroworld Festival tragedy in Houston this month.

One wanted to develop devices that would help people with heart problems — until his “heart stopped” at the show, according to his mother. Another was celebrating his 21st birthday with his best friend — who also died in the surge.

Another was killed trying to protect his fiancee in the crowd. And another, a 9-year-old boy, was watching the show from his dad’s shoulders before their father-son bonding experience turned horribly wrong.

The victims ranged from 9 to 27 years old, and at least 25 people were hospitalized.

Parents across the country whose children attended the Astroworld Festival on Nov. 5 are grieving the loss of these 10 victims, trying to come to terms with how a concert — an event where no shots were fired, where no natural disaster hit — could have turned into a mass-casualty event.

Authorities opened a criminal investigation into how the crowd surge occurred. For now, the victims’ family members are remembering who the young people were and grappling with the prospect of a future without them.

Here’s what we know so far about the victims.

Ezra Blount, 9

Ezra Blount was watching from his dad’s shoulders as Travis Scott performed from the elaborate stage.

The rapper was one of his favorite artists, and the 9-year-old had traveled from his home in Dallas to attend the concert, in what was meant to be a father-son bonding experience.

But things went horribly wrong.

When the crowd surged forward, his father, Treston Blount, struggled to breathe and lost consciousness, he later recounted in an online fundraiser. Ezra fell to the ground and was trampled.

Ezra was taken to a hospital and placed in a medically induced coma on life support, suffering from significant trauma in his brain, liver and kidney. He died Sunday, according to a statement released by the family’s attorneys, becoming the youngest person to die from injuries sustained at the festival.

“The Blount family tonight is grieving the ultimate, incomprehensible loss of their precious young son,” personal injury attorney Ben Crump and co-counsels Alex and Bob Hilliard and Paul Grinke said in a joint statement. “This should not have been the outcome of taking their son to a concert, a joyful celebration. Ezra’s death is absolutely heartbreaking.”

Crump is representing the family in one of many lawsuits starting to emerge from the catastrophic concert.

“Our city tonight prays for his mom, dad, grandparents, other family members and classmates at this time. They will need all of our support in the months and years to come,” Houston Mayor Sylvester Turner (D) said on Twitter on Sunday. “May God give them strength. RIP Ezra.”

The family couldn’t be reached for comment late Sunday.

In an interview with ABC13 last week, the boy’s father spoke tearfully about how traumatic it was to see his son on life support: “I’m not ready to lose my boy at all.”

John Hilgert, 14

Most high school freshmen fly under the radar. But John was one of those kids whom everyone knew and loved, said former baseball coach Justin Higgs.

He was an athlete and a big personality, always enthusiastic about recreational games like dodgeball and serious ones like flag football. Higgs, who coached John when he was 11 and played shortstop and catcher, said his late player had a tightknit family and many close friends.

“He just had a good attitude,” Higgs said. He added that many of his players loved Travis Scott and listened to his music extensively.

John was a ninth-grader at Memorial High School in Houston. A spokesperson for the Spring Branch Independent School District confirmed his death to The Washington Post.

“We are deeply saddened to inform you that a male ninth grade student died last night in an incident at the Astroworld Festival,” school Principal Lisa Weir wrote in a note to families. “Our hearts go out to the student’s family and to his friends and our staff.”

Tracy Faulkner, who has known John since he was a young boy, told the Houston Chronicle that he was “the sweetest and smartest young man.”

Faulkner’s son Robby Hendrix, 15, grew up playing sports with John. He also attended the festival with another group of friends. “They were both in the same place at the same time and one came home and one we will never see,” Faulkner said.

Axel Acosta, 21

Edgar Acosta recognized the white sneaker first.

Then he saw the photo of his son Axel’s lifeless face circulating on social media. For a fleeting moment, he thought he was sleeping.

“I told myself, he must be sleeping, maybe at the hospital,” he said. But hope faded quickly. “I wished God I was wrong, but I knew it is him,” he said. “I knew he was dead.”

Axel Acosta was born in Stockton, Calif., and raised in Yakima, Wash. He was a senior at Western Washington University studying engineering and computer science.

Acosta couldn’t wait to graduate and travel, his father said. He dreamed of visiting Mexico City, where his grandparents are from, to eat tamales and mole, his favorite dishes. Acosta was shy and studious, his father said, and proud of his Mexican roots. “Every father thinks their son is perfect; I was no exception to that,” Edgar Acosta said.

Axel Acosta had been looking forward to the thrill of live music after 20 months of the coronavirus pandemic, his father said.

His dad began to worry as he read the news of what happened at the Astroworld Festival late on the night of Nov. 5. He started frantically calling his son’s cellphone. Then he called the hospitals. There was no answer.

The next morning, Edgar Acosta learned his son had not made it back to his hotel that night. So he called the Harris County Sheriff’s Office to report that his son had been at the concert and was missing. “I knew something was wrong, otherwise he would have called,” he said.

By that night, a photo of Axel Acosta’s face and sneaker was released by the Harris County Institute of Forensic Sciences to the media. Officials said they couldn’t identify the body and asked for the public’s help.

Edgar Acosta saw the image on social media and said he knew immediately it was his son. He contacted authorities with evidence of knowledge only a parent can know: birthmarks, a dislocated knee, the shape of his left ear.

“As a father, no matter how beaten or disfigured your son is, you know your own son,” Edgar Acosta said. “I knew him when he was alive, and I know him now that he is dead.”

Franco ‘Cuauhocelotl’ Patino, 21

Franco “Cuauhocelotl” Patino was a few months away from graduating from the University of Dayton with a degree in mechanical engineering. The 21-year-old from Naperville, Ill., hoped to develop biomechanical devices to help people with heart problems.

His mother, Teresita Patino, told The Post that Franco’s “heart stopped” amid the crowd surge.

He was “a good friend and a good brother and a good son,” his mother said. “He was kind. He was always helping … everybody feel accepted and included. He was always hugging us.” He is survived by his parents, Teresita and Julio, as well as his brothers, Julio Jr. and Cesar.

Franco followed his older brother, Julio Jr., to the University of Dayton, where he last year helped launch a special interest house for Hispanic engineers to encourage them to reach their full potential in science, technology, engineering and math programs. The goal, he was quoted as saying in a university blog post, was to create “a little piece of familiar culture in a predominantly White institution.”

Patino, who attended the concert with his best friend, Jacob Jurinek, “saved for months” to purchase flights, hotel rooms and tickets as a celebration of Jurinek’s birthday, Teresita Patino said.

She said she hoped her son’s death would serve as a wake-up call for those who organize large concerts. Her son was at the concert “to celebrate and live life, happy and safely,” she said, “and I want whoever is in charge of these kinds of events to make sure this never happens again. … No mother should have to lose her son like this.”

Franco’s younger brother, Cesar Patino, asked on Twitter if anyone could share details of his brother’s final moments. In a photo accompanying the post, Franco is smiling in a queue of people gathered alongside a tall metal fence.

Early the next morning, Patino’s brother wrote: “I finally found the guy that helped my brother by giving him CPR.”

“Thank you all for making that happen remember his name,” he wrote in a photo tribute to his brother and Jurinek, who he said also died at the concert.

The university announced Patino’s death in a campuswide email, the student-run Flyer News reported. In the email, University of Dayton officials wrote of their “immeasurable grief” at losing Patino and another student who died in an unrelated incident.

On Twitter, the tributes rolled in from friends and fellow students. “RIP Franco,” wrote one user. “You were a bright light in every room you were in. A bright future cut far too short.”

Jacob Jurinek, 20

Ever since Jacob Jurinek’s mother died when he was 10, it was just he and his father, Ronald. “Him and I were just best buddies,” said Ronald Jurinek.

The father and son would take ski trips together and get out on the boat at the lake by their second home in Michigan.

Known as “big Jake” to his adoring younger cousins, Jurinek graduated from Neuqua Valley High School in Naperville, Ill., in 2019. He was a junior at Southern Illinois University in Carbondale, where he was studying art and media. He worked on graphic arts and media as an intern for the athletic department.

He bought the Astroworld Festival tickets six months ago to celebrate his upcoming birthday: On Nov. 20, he would have turned 21. He traveled to Houston with his best friend, Franco Patino. Patino never returned home, either.

Jurinek loved Marvel movies and pro wrestling, his father said, and.enjoyed watching his home teams, the Chicago Blackhawks, the White Sox and the Bears.

“He was the type of person who would do anything for anybody. He wasn’t ever in any trouble. He never gave me any trouble. His heart was bigger than his head,” Ronald Jurinek said.

The last time Jurinek talked to his father was on Nov. 4, letting him know he and Patino had arrived in Houston. They would then get up early the next day to catch all the activities at the festival.

“Every conversation we had always ended in ‘I love you,’ ” Ronald Jurinek said, his voice breaking. “That was the last thing we said to each other.”

Danish Baig, 27

Mirza Ammar Baig said his brother Danish Baig died as he lived — taking care of others.

“He was the kind of person that just made your day better,” Mirza Ammar Baig said. “He would always give more than he took. He was the center of happiness, the life of the show.”

Danish Baig was born in Pakistan. He grew up in Euless, Tex., with four siblings and worked as a district manager for AT&T in Crowley, Tex.

He attended the Travis Scott performance with his fiancee and another sibling, Basil Mirza. On Facebook, Basil recounted scenes of chaos at the show, with people “hitting pushing and shoving.”

“People were trampled, walked, and stomped on,” he wrote.

In his tribute, Basil said his brother died “courageously” trying to protect his fiancee. “I want you to know you passed the test of life,” he wrote. “Your bravery and your courageousness will never go unheard. You are everything and the world to me. I can’t believe you’re not with us no more.”

“I love you my brother,” Basil wrote. “I am scarred for life.”

Mirza Ammar Baig said authorities told him his brother died of cardiac arrest due to lack of air, but the exact circumstances of his death are still unclear.

Rodolfo Angel Peña, 23

A former wide receiver on his varsity football team, Rodolfo Angel Peña, known to most people as “Rudy,” was studying criminal justice at Laredo College in Texas. He hoped to one day work for U.S. Customs and Border Protection.

His hugs, smile and positive attitude will be missed the most, his family told Rolling Stone.

“Whenever we would feel down, he’d say, ‘Come here, I’ll give you a hug.’ He made us all feel better,” his sister Jennifer Peña told the outlet. At 23, Peña was the youngest of five siblings and “the calmest, the most playful,” according to his brother-in-law, Sergio Gonzalez, who gave an interview to People.

A music lover who enjoyed dancing, Peña was one of 50,000 people attending Travis Scott’s Astroworld Festival.

“We have a hole in our hearts,” Jennifer Peña continued, adding that the family was waiting for his body to be returned home. “We lost a very special person in our lives,” she said. “That concert took my little brother.”

Madison Dubiski, 23

Madison Dubiski’s frequent social media postings tell the story of a young woman who embraced life. On her Facebook page earlier this year, Dubiski wrote that she was “just living my best life with my people!!!” alongside a video compilation from recent social events: an Astros baseball game, a nightclub in Houston, a spa visit, a steakhouse, a shopping trip.

To mark her 23rd birthday in May, she beamed as she posed in a pink phone booth surrounded by flowers. In one hand she clutched a bottle of champagne, in the other a cluster of balloons.

“May all your dreams come true this year,” her mother, Michelle Dubiski, wrote in a birthday tribute to her daughter on Facebook.

Dubiski lost her life at Travis Scott’s Astroworld Festival. In a Facebook post, her cousin Chase Dowling paid tribute to her as “beautiful, compassionate, and loving.”

“There will forever be a piece of me missing,” Dowling wrote. “Your smile could light up a room.”

Bharti Shahani, 22

Bharti Shahani was so excited to attend the Astroworld Festival — her first music concert — that she picked out her outfit in advance.

The 22-year-old college student rarely asked her family for anything. So when she told her mother that she wanted to see Scott perform, her mother reluctantly agreed. The day of the event, Shahani eagerly headed out with her sister and cousin.

She never returned home.

“For the first time in her life, she wanted to have fun,” her sister, Namrata Shahani, told reporters after her death. “And that was taken from her.”

Shahani got separated from her sister at the concert. Her family found her at the hospital. She was declared dead five days later.

Shahani’s family described her as the responsible oldest daughter of her immigrant parents. She frequently cared for her sister while her mother worked at the family business. A computer science student, Shahani loved playing badminton, walking her 2-year-old Husky and picking up Dunkin’ coffee, her sister said.

Tributes poured in after the family announced her death.

“Our hearts are with the family of Bharti Shahani,” Houston Mayor Sylvester Turner (D) tweeted. “Please keep her family in your prayers, and remember all victims’ families as they grieve the loss of their loved ones.”

Brianna Rodriguez, 16

Brianna Rodriguez was a natural performer.

The junior at Heights High School in Houston had a passion for dancing and “could always make anyone smile,” her school band wrote on Twitter.

“Now she’s dancing her way to heaven’s pearly gates,” her aunt Iris Rodriguez wrote in a tribute on Facebook, describing her as “a beautiful vibrant 16-year-old” who was “the light of the family.”

With tears streaming down their faces and fresh flowers in their hands, Rodriguez’s family quietly gathered two days after the concert outside of the park where the teenager lost her life.

They arrived in small groups, greeting each other with long embraces, until about a dozen people huddled around a makeshift memorial on a fence on the edge of NRG Park. They wrapped their arms around each other, swaying above the candlelight.

One woman collapsed in tears on the street curb. A small boy bent down beside her and threw his arms around her neck.

Just after 7:30 p.m., the family began to pray together. And then they began to sing. “Un día a la vez,” — one day at a time — they sang in unison, their voices reverberating in the crisp fall air.

The family declined to comment to The Post.

“My heart aches so profusely for my brother Osvaldo Rodriguez and not my sister in law but my sister Ester Rodriguez,” Iris Rodriguez wrote on Facebook. “Brianna left this world leaving the biggest mark in everyone’s life.”
