Survivor recalls losing brother in deadly crowd surge at Astroworld music festival: "He did not deserve this!"

Some survivors of Friday's deadly crowd surge at the Astroworld music festival in Houston say authorities did not do enough to prevent the tragedy.

Eight people were killed when a crowd pushed forward, after rapper Travis Scott took the stage. Some in the audience were crushed, while others were desperately trying to get Scott's attention. But the concert continued for almost 40 minutes after officials declared a mass casualty event.

The oldest victim was 27 years old; the youngest was 14.
