A young man named Alejandro is photographed at his home north of Monterrey, Mexico, in June 2014. He is not affiliated with any gangs, photographer Tom King said, but he has lost a number of friends to violence. King spent two and a half years in the Monterrey area, trying to learn more about its young men and the brutality around them.
The mountain El Cerro de la Silla serves as the backdrop for Monterrey in this photo from July 2013. The San Rafael neighborhood, seen in the foreground, contains public and informal housing projects, King said.

Donaldo poses for a portrait at his home in July 2014. King said he has lost a number of friends to violence. "I wanted to understand why these young men were so vulnerable to this violence," King said. "What was happening in their world? Who were they? What was their reality?"

This machine-gun round was found outside a home in Monterrey after the Mexican army entered in January 2012, King said.
Shaky has lost a number of friends to violence, King said. "It's important to show that they're just, in my opinion, vulnerable young men on the boundary between adolescence and adulthood and trying to work out what they're supposed to be doing in life," King said.
