HOUSTON: A 9-year-old Dallas boy has become the youngest person to die from injuries sustained during a crowd surge at the Astroworld music festival in Houston.

Ezra Blount of Dallas died Sunday at Texas Children’s Hospital in Houston, family attorney Ben Crump said.

Ezra was placed in a medically induced coma after suffering serious injuries in the Nov. 5 crush of fans during a performance by the festival’s headliner, rapper Travis Scott.

He is the 10th person who attended the festival to die.

“The Blount family tonight is grieving the incomprehensible loss of their precious young son,” Crump said in a news release Sunday night. “This should not have been the outcome of taking their son to a concert, what should have been a joyful celebration.”

Treston Blount, Ezra’s father, described what happened Nov. 5 in a post on a GoFundMe page that he set up to help defray Ezra’s medical expenses. He said Ezra was sitting on his shoulders when a crowd surge crushed them. The father lost consciousness and when he came to, Ezra was missing, Blount said. A frantic search ensued until Ezra was eventually found at the hospital, severely injured.

The child incurred severe damage to his brain, kidney, and liver after being “kicked, stepped on, and trampled, and nearly crushed to death,” according to a lawsuit his family has filed against Scott and the event’s organizer, Live Nation. The Blount family is seeking at least $1 million in damages.

The others who died ranged in age from 14 to 27. Some 300 people were treated at the festival site and 13 were hospitalized.

Houston police and fire department investigators have said they are reviewing surveillance video provided by concert promoter Live Nation, as well as dozens of clips people at the show widely shared on social media. Investigators also planned to speak with Live Nation representatives, Scott and concertgoers. Scott and the event organizers are now the focus of a criminal investigation.
