Federal firearm charges have been filed against an undocumented immigrant acquitted in San Francisco last week in the shooting death of Kate Steinle.
Jose Inez Garcia-Zarate admitted to the killing of Steinle in 2015, but said that the gun he found under a San Francisco bench went off accidentally.
The state conviction carries a maximum sentence of three years in jail, while each new federal charge carries a maximum sentence of 10 years.
He added that Garcia-Zarate would ultimately be deported.
The Justice Department said that the federal charges are the result of an investigation by the federal Bureau of Alcohol, Tobacco, Firearms and Explosives. He was indicted on one count each of being a felon in possession of a firearm and ammunition and being an illegally present alien in possession of a firearm and ammunition.
Deputy District Attorney Diana Garcia said in her opening statements in October that Garcia Zarate "meant to shoot" at people, the San Francisco Chronicle reported.
Last week a San Francisco jury found Garcia Zarate, 45, not guilty of murdering the 32-year-old Kate Steinle as she was walking along a city pier two years ago.
Legal experts have said prosecutors overreached by asking for a first-degree murder conviction because the fatal shot ricocheted off the ground, supporting Garcia Zarate's defense that the shooting was an accident.
Zarate was acquitted of first and second degree murder and involuntary manslaughter on Thursday. The case has sparked national outrage over sanctuary cities, and the need for stricter laws on illegal immigration.
Gascon on Tuesday called Trump a "madman" for a series of tweets deriding the jury's verdict. Garcia Zarate was released in San Francisco two months before Steinle's death despite a request from immigration authorities to turn him over for deportation.
Authorities said the gun Garcia Zarate used was stolen from the vehicle of an off-duty agent for the Bureau of Land Management.
Sessions slammed the verdict Friday, telling Fox News that "it's time for this country to get its head on straight" because sanctuary cities like San Francisco "should not be protecting criminal aliens".
