May I insert some things on behalf of other family members that aren't here to fine-tune things?
Judy knew something was wrong because Renee insisted she pick her up at Granny's by 4 o'clock and take her home to get ready for the party that night. If a 14 year old misses the "curfew" she set. Something's wrong. Judy was the red-flag that set the phone calls in motion, but they began at 4pm, not 2pm. She had Granny (Mrs. Swint) coordinating communication with the Moseley's - across the street from her. She focused on Francis and Cotton because she had no idea how to reach Tommy directly. Debra was at the house on Minot. Everyone was a prisoner of telephones plugged into walls without call-waiting, caller ID, or any advantage we take for granted. I would love to see those phone calls on a spreadsheet. I can't imagine any of those people remembering with much accuracy who they talked to at what time or in what order. It's giving me a headache. Other than the Arnold's being in up to 3 places at once - the way that day unfolded is in fair agreement. There are two seats at the table that have been unfilled for 20 years at least. If the core family members want to fine-tune their recollections it should be PM where they can work it out privately.
