HOUSTON — Despite the sweltering heat, María Guadalupe Rodriguez kneeled in front of the makeshift memorial for Lorenzo Salgado Araujo, a man killed Tuesday by federal immigration agents. Rodriguez, a U.S. permanent resident and a longtime neighbor of Magnolia Park, the Houston neighborhood where the shooting happened, wiped her tears as she prayed. "I feel rage," Rodriguez told NPR in Spanish. Salgado Araujo was a 52-year-old Mexican national who worked in construction for more than three decades.
