Involuntary manslaughter in California occurs when one person kills another unintentionally, either
1.while committing a crime that is not an inherently dangerous California felony, OR
2.while committing a lawful act which might produce death, without due caution.1
Under California Penal Code 192(b), the key feature of California involuntary manslaughter is that it does not require intent to kill another person—unlike Penal Code 187 murder, which requires “malice aforethought.”2
Whether it was an "Accident" or whether he aimed at her is immaterial to that charge if he didn't show due caution when handling a firearm, which he didn't if he accidently discharged it. Secondly, it is very convenient that he "found" the stolen gun isnt' it because possessing the stolen firearm might involve case 1. So, your defense of the verdict means that if the prosecution has proof that a gun was stolen, you had it, you shot it, and it kills someone, but you assert, Honest Injun! that you didn't steal the gun, and you didn't MEAN to shoot it, and you neither confess nor is there a witness or camera to show you shooting it on purpose, you walk free? Honest I swear I didn't mean too! becomes a lib's get out of jail free card.
Azarte's immigration status is relevant in two respects. First, even if we buy your naïve and credulous theory of accidental discharge (which itself is illegal and negligent) **He Should Not Have Been There**. He only was because of Liberals treating his kind of law breaking as a special kind, because he is not American and not white, two sacred categories, therefore they gave him sanctuary from the law. Second, not believing that the Lib San Fran Trump Resistance jury considered his sacralized status is like believing the black ladies who acquitted OJ didn't consider he was a black man who killed one of those blonde bitches stealing their men, or believing that Harvard really gave no preference to a minority "Indian" woman over say a white man for Law School hiring.
In both cases, you defense relies on credulity of those who protest they didn't do anything wrong, promise.
