In this July 17, 2015, photo, flowers and a portrait of Kate Steinle remain at a memorial site on Pier 14 in San Francisco. Jose Ines Garcia-Zarate, a Mexican national who touched off a fierce immigration debate for his role in the shooting death of Steinle, is seeking to overturn his felony illegal gun possession conviction, the only charge he was found guilty of after a jury acquitted him of murder.
