A nine-year-old boy who was on life support after being trampled at the Astroworld Festival has died, the tenth and latest death resulting from the crowd surge at the Travis Scott concert in Houston earlier this month.

The Dallas boy, Ezra Blount, sustained brain, liver and kidney trauma, according to a statement released Sunday by family attorney Ben Crump. He was subsequently placed in a medically-induced coma on life support before dying from his injuries, making him the youngest person to die as a result of the incident.

A nine-year-old boy who was on life support after being trampled at the Astroworld Festival has died, the tenth and latest death resulting from the crowd surge at the Travis Scott concert in Houston earlier this month.

The Dallas boy, Ezra Blount, sustained brain, liver and kidney trauma, according to a statement released Sunday by family attorney Ben Crump. He was subsequently placed in a medically-induced coma on life support before dying from his injuries, making him the youngest person to die as a result of the incident. 

Mr. Crump’s statement said a lawsuit was filed naming several parties, including Mr. Scott, alleging negligence relating to crowd control, failure to provide proper medical attention and inadequate training that contributed to Ezra’s death. 

“The Blount family tonight is grieving the incomprehensible loss of their precious young son. This should not have been the outcome of taking their son to a concert, what should have been a joyful celebration,” Mr. Crump said in a statement on Sunday. “Ezra’s death is absolutely heartbreaking. We are committed to seeking answers and justice for the Blount family. But tonight we stand in solidarity with the family, in grief and prayer.”

Houston mayor Sylvester Turner offered his condolences to the Blount family Sunday night on Twitter.

“Our city tonight prays for his mom, dad, grandparents, other family members and classmates at this time,” Mr. Turner wrote. “They will need all of our support in the months and years to come,” Mr. Turner wrote. 

Attorneys representing Mr. Scott weren’t immediately available for comment on Monday.

Mr. Scott’s lawyers have said the rapper didn’t know what was happening in the crowd of more than 50,000 fans at his show. While it appeared like Mr. Scott performed a full set, “when he was told to stop, he stopped—and it was an abbreviated set,” said David Byrnes, one of Mr. Scott’s lawyers. Mr. Scott learned of the police’s declaration of a mass casualty incident and the deaths early the next morning, his lawyers have said.

The Houston Police Department launched a criminal investigation probing the festival, where hundreds were treated at a field hospital, according to Houston’s fire chief. 

Houston Police Chief Troy Finner said last week that an investigation would take weeks or months. The causes of death for the deceased are pending.
