A 17-year-old YouTube star insulted a notorious drug lord. The teen was found with at least 15 bullet wounds.

Juan Luis Lagunas Rosales was born in the Mexican state of Sinaloa, a center for cartels and the land of notorious drug lord Joaquín “El Chapo” Guzmán. Lagunas grew up never knowing his father. His mother left him with his grandmother as a child.

Lagunas left his hometown at the age of 15 without finishing high school, moving to the nearby municipality of Culiacán and washing cars to make a living, he said in an interview in July. It was in this adopted town that he took on the nickname that would later become known across cyberspace: “El Pirata de Culiacán,” or “The Pirate of Culiacán.”
