Liz Sullivan, also known as Liz Steinle, is the mother of Kathryn 'Kate' Steinle, a 22-year-old woman who was fatally shot on July 1, 2015, on Pier 14 in San Francisco by Jose Ines Garcia Zarate, an undocumented immigrant with a history of deportations and criminal background. The tragic incident sparked national debates on immigration policy, sanctuary cities, and border security, with Kate becoming a symbol for advocates of stricter immigration enforcement. Sullivan, married to Jim Steinle, publicly grieved their daughter's death and channeled their loss into advocacy, testifying before Congress in 2015 and 2016 on the failures of sanctuary city policies and the need for immigration reform. Their story was prominently featured in political campaigns, including endorsements of Donald Trump's 2016 presidential bid, where they spoke at the Republican National Convention to highlight the human cost of lax immigration laws. Following Kate's death, Sullivan and her family pursued civil action against the city of San Francisco and the federal government, alleging negligence in immigration enforcement and sanctuary policies. The lawsuit was settled out of court in 2019 for an undisclosed amount (Source B provides a more specific date than Source A's 2017). Sullivan serves as the Advocacy Spokesperson for Steinle Family Advocacy, an NGO focused on supporting families affected by crimes committed by undocumented immigrants and promoting policy changes to prevent similar tragedies. Her advocacy work underscores the personal impact of policy decisions, positioning her within networks of conservative immigration reform groups and political figures focused on law and order themes, including partnerships with organizations like the Federation for American Immigration Reform (FAIR). Sullivan's advocacy has been marked by both support from conservative groups and criticism from immigration rights advocates who argue the case has been politicized. Despite the shooter being acquitted of murder charges in 2017, the Steinle family continued their efforts, maintaining a public presence through media appearances. Sullivan's personal life remains relatively private beyond her public role as an advocate. Residing in the San Francisco Bay Area, she has emphasized family values and justice in her public statements, contributing to broader discussions on crime, immigration, and government accountability.
