The 10 people who lost their lives in the massive crowd surge at the Astroworld music festival in the United States died from compression asphyxia.
Medical examiners in Houston had to wait several weeks following rapper Travis Scott's November concert for additional test results before making their final report.
Some 300 people were injured and treated at the festival site after fans surged towards the stage - squeezing people so tightly together they could not breathe or move their arms.
There were 25 people taken to hospitals, and the youngest victim to die was nine-year-old Ezra Blount.
Dozens of lawsuits have been filed over injuries and deaths at the concert, and Travis Scott and the event organisers are the focus of a criminal investigation by Houston Police.
