With regard to the "party"...
This is an excellent point, and I hope this is one of the instances where LE is going back from the beginning and cross-checking everyone's stories. If there was indeed a party of any sort and Auntie was there, she has firsthand knowledge of it. OR, Auntie was NOT there and knows about it secondhand - how does she know it/who was the source?
"Some people are saying she stopped by a party after that," said Chambers. "We think whoever called her over to them was asking her to go to that party, because where she was found and where the party was aren't very far apart." (Huffington Post article previously cited)
Whatever the party was, apparently it had a set location and an address close to 2300 Herron Road... but who provided that information?
BBM: If I am not badly mistaken, Auntie Sha Sha said in that interview, "I was there."
