If a 6 yr old were to take off by herself OR an adult said gather up your things because we are leaving, do you really think they would take their toothbrush and toothpaste? I'm thinking it's more likely she would grab a toy or stuffed animal , a game, a book, etc. not her toothbrush.. It doesn't make sense. A random kidnapper wouldn't take time to take those items. If they wanted it to seem like she left willingly, it seems they would take more personal items that she was attached to. Maybe that is not all that is missing and mom just hasn't realized it yet. Most kids that age have a zillion toys. Do you really think you could look in your kids room at any point in the day and say 'oh ok, red bear is missing the blue stuffed dog and her 2 barbies are gone'?
