Houston is a good 5 hr drive from here, so while it's possible, unless you can tie mom to this area via family or something, I would think it's doubtful . Maybe a close friend or family who lived up here decided to 'help' mom out ? But again, between Houston and here are millions of acres of farm and ranch and grasslands, why come all the way up here to a residential street? I'm not going to discount it totally but if this is the same baby, what a strange group of people associated with her.
ETA Not to mention there is a huge OCEAN much closer to Houston, which would seem a far more likely ' resting' place

mooo
