The 10 people killed at the Astroworld music festival in Houston, Texas, last month all died from compression asphyxia during a massive crowd surge, officials announced Thursday.
Medical examiners with the Harris County Institute of Forensic Sciences in Houston had to wait several weeks following the November 5 concert hosted by Travis Scott.
Medics had to wait for additional test results before making final determinations on cause and manner of the deaths, CBS News reports.
At the time of the tragedy, a section of the 50,000-strong crowd began rushing towards the stage during the rapper's performance.
Festival-goers affected by the crowd surge struggled to breathe, with some losing consciousness, and, as a result, were trampled on by other attendees at the concert.
According to the medical examiner, all ten victims died of "compression asphyxia," per CBS News.
The report states each victim was pronounced dead at local hospitals. One of the ten victims had "contributory cause" to his death, a combination of "toxic effects of cocaine, methamphetamine, and ethanol."
Those who tragically lost their lives include John Hilgert, 14, Franco Patino, 21, Jake Jurinek, 20, Danish Baig, 27, Brianna Rodriguez, 16, Axel Acosta, 21, Rudy Peña, 23, Madison Dubiski, 23, Bharti Shahani, 22, and Ezra Blount, nine.
Some 300 people were injured and treated at the festival site and 25 were taken to hospitals.
More than 300 lawsuits have been filed over injuries and deaths at the concert.
The rapper and the event organizers are the focus of a criminal investigation conducted by Houston police. No one has been charged as of yet as the investigation is ongoing.
According to Forbes, Scott's representative maintains that he did not have the authority to stop the concert.
His rep added that although he was "not responsible" for the crowd surge, he wants to be "responsible for the solution."
Following the tragedy, Scott offered to pay for all of the victims' funerals, but half of the grieving families rejected the gesture. The family of the youngest victim, nine-year-old Ezra Blount, was among those who declined the offer.
Speaking on those rejected offers, Scott told radio presenter Charlamagne Tha God in a recent interview: "All things are understandable. At the time they're grieving and trying to find understanding, they want answers. I've got to just continue to show up for that."
