She may not have known anything about Adrianna, the missing ex. It looks like she wasn't given much media exposure as a missing persons..
As for mom not knowing about the type of guy Grant is.. For now, I think I'll give her the benefit of doubt. I came to WS in May to follow the Mickey Shunick case and I quickly got hooked. I read tons of threads here daily and I'm just baffled that SO MANY PEOPLE are missing or murdered. I would never consider myself naive but I still read things here that shock me daily. I know the world is full of evil. I have young children and if it wouldn't psychologically and socially damage them, I would be temped to build a bunker for us to all live in, protected from the evil. Since that's not possible, I have been making changes to be more aware, more safe. Because of this case, if I were to find myself a single mom in the future, I will be doing some background checks on whoever comes around my children. It honestly never occurred to me before, so I can understand and sympathize with Gabbiee's mom about her not doing it on Grant. I am sure she is feeling the guilt and blame enough but it's important to remember that the blame lies squarely with Grant. He made the choice to abduct Gabbiee. He may have made the same choice even if she were a complete stranger to him...
