I keep thinking back to when the searchers were looking for Elizabeth (in the area that we now know she was being held - near her home) immediately after her disappearance when searchers saw people in the same area with one fitting Elizabeth's discription. I thought then and especially now, why didn't they send up a helicopter that night with heat seeking capabilities (as they do for criminals on the lamb)? Indeed!

I thought they had sent out helicopters with heat seeking devices. I'll have to find a source later.
