Xavier has a bit more. Including this:
The claim said that when Arambula fell to the floor, Lilly shot him two more times. That's when Arambula told Lilly he'd shot the wrong man. In his Internal Affairs interview, Lilly admitted firing at Arambula without any verbal warning, according to the claim.
Oh, boy. If either of those is true, the cop is screwed. And rightly so. And so is the department for trying to cover it up.
