The Venezuelan migrant who shot and killed 18-year-old Sheridan Gorman as she walked at night to view the northern lights has been identified as Jose Medina-Medina. The name of the 25-year-old suspect was not previously released because he had not yet been charged.DHS announced Sunday that ICE has filed an arrest detainer, asking “sanctuary politicians” not to release Jose Medina-Medina, a Venezuelan criminal illegal alien arrested for the murder of 18-year-old Sheridan Gorman in Chicago, Illinois.According to local reports, Sheridan Gorman, an 18-year-old Loyola University student, was shot dead around 1:00 a.m. Thursday while she was walking in a park with friends. Medina-Medina is accused of approaching them wearing a mask and armed with a gun. As he tried to run away, he opened fire with his gun. Gorman was shot and pronounced dead at the scene.DHS said Medina-Medina was apprehended by the U.S. Border Patrol on May 9, 2023, and released into the country under the Biden administration. He was released again on June 19, 2023, following his arrest for shoplifting in Chicago, Illinois.Acting Assistant Secretary of State Lauren Biss said, “Sheridan Gorman had her perfect life before this brutal killer decided to end her life. She was failed by open border policies and sanctuary politicians, who twice released this illegal alien before he committed this heinous murder.” “We are calling on Governor JB Pritzker and Chicago’s sanctuary politicians to commit to not releasing this criminal illegal alien from prison back into American neighborhoods.“Her family wrote in an online obituary for the teenager, “Sheridan was everyone’s cheerleader in every sense of the word. She had a way of making people feel valued, appreciated and believed.” The obituary said, “She radiated something even greater – a rare and unmistakable warmth, a spirit that was vibrant, kind and full of life. She was funny, kind and deeply loving, with a heart that made room for everyone.”
