The 10 people who lost their lives in a massive crowd surge at the Astroworld music festival in Houston died from compression asphyxia, officials have announced.

Medical examiners with the Harris County Institute of Forensic Sciences in Houston had to wait several weeks following the November 5 concert by rap superstar Travis Scott for additional test results before making final determinations on cause of the deaths.
