well..I'll stake a stab at it..
First of all whomever blugeoned this victim was targeting her..no attempt to steal anything from the household full of good electronics. Personal items removed i.e wedding rings. then leaving a living witness along with actually taking the time to care and settle the child..and careful cleanup of all items..such as blood, diaper of child, weapon, no garbage nor doggie prints (had to have been removed from BR his usual sleeping area) Lights on throughout house during night (330AM witness) yet all turned off when left..
Whomever did this knew the house, new the child, knew where things were. This was a personal murder and NOT a random or stranger.
Question??..Why not take the Lexus from the garage? keys were available. Why not steel the purse on floor in Kitchen??..The absence of evidence in this case is in of itself EVIDENCE..
Bottomline..murderer was related, connected and the rage shown means it was personal!!
