There are so many unknowns here, which is strange since it seems like there are possibly so many people involved. What always surprises me about cases of people who act “weird” and somewhat paranoid and who are otherwise normal, functional people is this: why didn't they tell anyone? If he was known as some sort of narc and potentially snitched on someone for drugs, did someone say something to him that scared him so much that he kept his mouth shut? In my experience, someone who is quick to raise the alarm about illegal behavior will go directly to the authorities or at least to his parents if he feels threatened. Anyway he would be leaving soon...
Later on at this point, if he was so paranoid, why on earth would he approach a car at that hour and lean into it? Presumably she knew and trusted the driver, so I doubt it was any of the seedy characters at his job. If I were one of the people who suspect him of ratting them out, I'm sure he would have run into the house...
As for the beer...I don't give much credence to family and friends saying he wasn't a big drinker after the fact. Family doesn't necessarily know and friends would want to preserve his reputation. However, I find it extremely strange to have a cooler of beer in the trunk if you're not planning on going to a party or something. I tend to think Chito was lying about that. People lie about really strange things when questioned by authorities...
But if there was beer in his trunk, is it possible that that night he was going to a party and someone he didn't know very well, but was kind of an acquaintance, showed up to give him a ride and then took him away? ? Did she take him somewhere to be “taught a lesson,” which then got out of control and led to his death?
Most likely he is already dead...
rest in peace
