The ruling, dated Dec. 22, casts doubt on Rialmo’s account of events and turns in part on investigators’ determination that the evidence indicated that LeGrier did not swing the bat at Rialmo, as the officer has said. Investigators also found that the evidence — including shell casings, witness statements and forensic analysis — also suggested Rialmo was farther away from LeGrier when he fired than the officer has said. LeGrier fell in the vestibule of an apartment building, and Rialmo said he opened fire from the building’s front porch, but investigators determined it was more likely the officer was between the bottom of the porch and the sidewalk out front.
