Over the past decade, photojournalist Timothy Fadek has built up a solid career covering the big stories in all the hot spots -- Iraq, Israel, last year's war in Lebanon -- but he also seeks out those stories that matter most to him: the crushing poverty in Haiti, the passion of the Christian right, a "hip-hop church" in Queens. Nowhere is his commitment to such journalism more apparent than in his long personal project on Juárez, Mexico. For years, Fadek has been traveling to the troubled border town between Mexico and Texas to document a ghastly legacy -- the murders of more than 400 women over the past decade. Jay DeFoore, editor of PopPhoto.com and himself a native of Texas, has followed Fadek's painstaking work on the story. Here DeFoore describes Fadek's personal journey.
