At a morning press conference, District Attorney Michael Hestrin said his decision was in accordance with a grand jury's recommendation that LAPD Officer Salvador Sanchez not be charged in the case.
Kenneth French, a 32-year-old man described as developmentally disabled by his family, was killed in the shooting. His parents, Russell and Paola French, were wounded by gunfire and hospitalized.
Sanchez's attorney has said the incident began when the off-duty policeman was assaulted while holding his toddler son, and contended that Sanchez opened fire after being knocked to the floor.
