A federal appeals court in California ruled that the parents of Kate Steinle, a woman fatally shot by an unauthorized immigrant in July 2015, cannot sue the city of San Francisco for failing to notify immigration officials of his release from a local jail weeks before the killing.

A three-judge panel of the 9th Circuit Court of Appeals, in a unanimous decision, ruled that San Francisco's then-sheriff, Ross Mirkarimi, violated no federal, state or local laws when he released Juan Francisco Lopez-Sanchez, also known as José Inez Garcia Zarate, on a minor marijuana charge without notifying Immigration and Custom Enforcement.

The ruling upholds a lower court in dismissing "a general negligence claim" against the city filed by Steinle's parents. Their suit alleged that Mirkarimi drew up a memorandum instructing city employees to limit the information shared with federal officials about the release of unauthorized immigrants from the San Francisco jail.
