(Portland, OR) -- Oregon health care workers are paying tribute to an ICU nurse gunned down and killed by ICE agents in Minneapolis Saturday. Nurses and other residents gathered outside the Eugene Federal Building yesterday afternoon for a vigil for 37-year-old Alex Pretti. ICE agents shot and killed Pretti Saturday, just weeks after a federal ICE agent shot 37-year-old Renee Nicole Good in the face and killed her in the same city. Hours before yesterday's vigil, federal agents violently pushed back against demonstrators protesting ICE outside the federal building. Witnesses say agents pushed protesters down and used pepper spray against them.
