I am thinking this Juan is the guy. Lots of circumstantial evidence, but hear me out.
He is listed as a suggested friend on the W's secret FB account. His FB page has very little information. It appears that he does have a kid though. And he has a friend that is listed as working at my W's job. And his picture looks a lot like the ones on her phone. Again, the pictures on the phone are not clear, but they do look a lot a like.
Must continue to gather evidence though. I got a gift this morning though.
