I think she is plenty sophisticated. She created an LLC almost 20 years ago for her cleaning business, although she hasn't filed the required paperwork since the first year, so it was rendered inactive/forfeited. She set up a "go fund me" page to help with expenses for Mrs. Figueroa's family. She has put herself at the center of the investigation, giving interviews virtually non-stop for the first few days (with a break to have the manicure so she would be camera-ready) and releasing texts and voice mails from her murdered clients. LE can not have loved that.
I wouldn't assume she helped raise the children. She owned a business where she employed other cleaners, such as Mrs. F. (according to her) and had at least several other clients, so she wasn't full time at any home. She may have nothing to do with the crime, but she has chosen to speak to anyone with a microphone who would listen (more than once with her name and face showing - different outfits) and given out conflicting information so that at least some of it can't possibly be true. This is strange if not suspicious behavior. She may not be well-educated, but that doesn't mean she is a naif.
