If Sergio was not involved, I keep circling back to his dad being a possible suspect. I hate making assumptions like that, and it's not entirely fair, but the bounced checks written by his dad bother me. It's purely speculation/imo, but why would his dad say that happens sometimes, and then money problems are reportedly still going on to this day with his company? This would make sense if the life insurance never paid out or did pay out but Sergio wanted nothing to do with his dad and thus, would not help him pay off his debts. Again, speculation, but could the bounced checks be indicative of his dad paying someone off to take the hit out on Liz? This would be dumb given all the other planning, since it would look suspicious and could be traceable (maybe, I'm not sure), but could explain partially why the Texas Gang Unit is involved?
It would be a lot harder to trace a shooter to a random migrant who possibly worked for his dad, but his dad takes out money over a few checks to pay the person off ahead of time, and waits until his son leaves for work so he can get the life insurance b/c it won't look suspicious (this was poorly planned if so, b/c Sergio looks very suspicious). The motive in this whole case could be money, to pay off his debts and perhaps save his family/marriage. I'm just spitballing though, b/c I waiver back and forth between Sergio being reasonable and innocent, and then not lol. I hope he's innocent though and it seems like someone close to him and Liz could have done this without Sergio knowing/having involvement. If that's the case, I could see his sketchy dad being behind this. Doesn't his dad also have a lady friend in Miami FL where the search warrant was issued? Maybe the car was connected there too? Again all of this is IMO, but I just can't shake those bounced checks right before she's killed in a hit-like-style. Plus, his dad could've reasoned that using a cheap Star Wars disguise would point police to a different pool of suspects; a red herring. If anyone could help clear up some of what I mentioned, that would be much appreciated! These are things I've read and I'd love clarification on if any of my facts are wrong. Thanks!
