What they're saying:Nurses and community members gathered in honor of fellow health care worker Alex Pretti. Austin-area nurses, health care workers, and community members took time Wednesday evening to remember one of their own, 37-year-old Alex Pretti. "This affects us a lot because Alex was a nurse," Gonzalez said. The Department of Homeland Security confirmed that two federal immigration officers shot and killed Pretti on Saturday, Jan. 24, in Minneapolis, marking the second deadly shooting by federal agents there this month. DHS is taking the lead on the investigation amid calls for Homeland Security Secretary Kristi Noem to step down.
