Two days after a police projectile sent 18-year-old Dilan Cruz to the hospital, his sister spoke at his high school, pleading for peace in Colombia after five straight days of anti-government protests.

“What we want most right now is for him to recover,” his sister, Denis Cruz, said Monday. “We want what happened with Dilan not to be used for more riots, to create more violence.”

“The only thing we’re also asking for from my family,” she said, “is peace.”

But that night, Dilan died of the head injury, and protesters again flooded into the streets of Bogotá on Tuesday, calling the teenager a victim of police brutality.

The death has fueled still more anger among the tens of thousands of people who have for days protested against corruption and the conservative policies of President Iván Duque.
