In this Friday, July 17, 2015 photo, flowers and a portrait of Kate Steinle remain at a memorial site on Pier 14 in San Francisco, Calif., for Steinle who was gunned down by Juan Francisco Lopez-Sanchez, a Mexican citizen who authorities contend was in the country illegally. Lopez Sanchez, who was deported five times, admits fatally shooting Steinle while she walked with her father on the San Francisco pier crowded with tourists. He has said the shooting was accidental and has pleaded not guilty to second-degree murder. (Paul Chinn /San Francisco Chronicle via AP)
