How is she going to cover for him? She was at work. She doesn't have access to the car or apartment and didn't have access to those things before the police did, so I don't see how she would be able to cover for him i.e. remove or clean up evidence, etc. She could be telling the police he's a great guy and she loves him and blah blah blah. Maybe she is, I don't know, and I don't really care if she is, because that doesn't cover for him. JSO knows Ruben isn't a nice guy, so I don't see how singing his praises (if she even is) would help him in the long run.
I don't know. I just don't see a cover up being effective.
IMO
