America’s Wall

This isn’t President Trump’s wall. This is America’s wall. A months-long investigation led by Jean Guerrero with her team at KPBS and inewsource revealed never-before-published details about how construction on the existing U.S.-Mexico border fence pushed illegal cross-border traffic into the desert, into the ocean, into the earth and into the sky. Jean also sought out people whose lives have been shaped by America’s wall. The web series was an unprecedented digital innovation for the newsroom.

Border Wall Designs Deemed Breakable

A U.S. Customs and Border Protection report obtained by Jean Guerrero through FOIA shows new border wall barriers could fail to keep people from breaking into the U.S. — at least if they’re based on the steel and concrete barriers tested in last year’s $5-million Otay Mesa prototype project. The heavily-redacted report reveals that every single mock-up was deemed vulnerable to at least one breaching technique. Read her investigation.

Abuses Against The Deported

What happens to people deported from the U.S.? Jean Guerrero wanted to find out. She followed the plight of deportees for more than a year in a series of investigative reports that took her into Mexico’s sewers and won first-place San Diego Press Club awards, including Best Of Show, shedding light on human rights violations. Tijuana’s police chief was asked to resign the night the final report in this series aired on PBS NewsHour.

Hundreds Dying At The Border

Jean Guerrero journeyed into one of the deadliest smuggling routes at the U.S.-Mexico border to tell the story of the men who risk their lives to save lost migrants. She filmed a majority of the TV pieces on her iPhone. A version appeared on PBS NewsHour and Part I won the Sol Price for Responsible Journalism from the Society of Professional Journalists.

Asylum Seekers, Refugees, Immigrants And Detainees

Jean Guerrero has been telling the stories of asylum seekers, refugees, immigrants and detainees who allege abuses by U.S. officials or face unique challenges in this country. Start by reading about Jose Demar Fuentes, who came to the U.S. fleeing violence in El Salvador with his 1-year-old son, Mateo. His son was taken by immigration officials.
