Last month, a thrice-deported illegal immigrant with a long history of violent crime stabbed five people, killing two, John Paulson, 45, and Kimberly Susan Fial, 55, at the Grace Baptist Church in San Jose. The suspect, Fernando De Jesus Lopez-Garcia, has been in and out of prison, but Santa Clara County’s sanctuary policies prohibit any cooperation between local officials and federal immigration authorities. ICE has issued multiple requests for his detention, including one last summer, when he was sentenced to 327 days in prison for inflicting corporal injury on his spouse. Though Lopez-Garcia has a criminal record that also includes convictions for assault with a deadly weapon, battery of an officer, and vandalism, local officials were barred from letting ICE know when he was in custody.
