The Home Depot videos (or their mention of existing) were released in a 4-08-11 Doc dump previously linked on this thread and the dates are:
24. CD-R - Home Depot Video, 5-23-08, 6-29-08, 7-5-08
25. CD-R - Home Depot Video, 5-29-08
Two of them are obviously well before Caylee died, so if there is any evidence of her buying chemicals, masks, duct tape, etc. in Ma it will point to premeditation. The one on 6-29 might be her looking for a gas can and who knows what she was there for the day AL was returning home.
It's odd to me that she would be spending any stolen money on anyone but herself unless it was something important. I mean, it's not like you can buy sunglasses, bras and beer at Home Depot.
