Interesting. GF says "nephews" that were Haleigh's age - so that means at least two children 4 - 5 - 6 yrs old. Welp, those kids didn't come over by themselves!!!!! What adult or adults were with those "nephews"?
Those adults need to be questioned - what if one excused himself to go to bathroom - everyone is sitting outside so as to watch the kids play. Guy goes in house - goes to bathroom - scopes out the lay-out of the house - UNLOCKS THE DEADBOLT ON THE BACK DOOR - and then goes back outside to rejoin the group. Could be the cinderblock was already "around" or perp brought it back in case the deadbolt was caught and locked again. Sitting around chit-chatting while the kids played would lend HUGE insight as to the "routine" of the family. BF works 3 PM -3 AM, kids in bed by 8 - 8:30, she goes to bed around 10 probably so she can get back up when bf comes home - maybe make him something to eat, whatever.
Yep yep yep - I wanna know WHO these "nephews" are - her's? the bf's? the ex's? and, more importantly WHO BROUGHT THEM OVER TO PLAY. Perp could be "just a friend of the adult that brought the kids over. Kinda like "hey, I'm gonna take the kids over to Ron's to play - wanna come with me?" type thing.
