EXCLUSIVE: WHERE HANNAH WAS FOUND
POSTED ON OCT 19, 2014
Another source with whom I have spoken just this morning, confirms that on Sunday October 5, a long-time resident of Albemarle County drove by this residence and noticed an unusual flurry of buzzards behind the home.
Earlier the following morning, Monday October 6, this same man stopped his car at this residence and looked around. The buzzards had gone. This man knew the home to be a rental that was not currently lived in.
He walked the property, but only briefly since he felt odd that he was trespassing. He got back in his car and left.
Later that same morning, at exactly 9:45am October 6, he called the tip line, reported the address— 3193 Old Lynchburg Road— and said he’d noticed the buzzards. He also reported that he was concerned the property had not yet been adequately searched since the home was not currently lived in.
and that folks is all I got. Like I said earlier, it really doesn't matter, tips were called in, they were missed or not followed up on. But at the end of the day Hannah was found, and I believe after some down time LE went back and looked at all the tips (I remember they had some down time) and when Chesterfield LE came to volunteer they went to the area and found this precious child.
I certainly won't Monday morning quarterback anyone in this case. Thankful tips were called in and thankful LE found Hannah.
