Some updated opinions i have after today's dox release:
1) Docs state that Along with RA's 40cal sig they also took his clothes,jacket and BOOTS...I believe they matched boot prints from the scene to his boots .The dox state one eye witness stated RA looked bloody and MUDDY. Muddy means wet..wet means boot prints
2) RA during his first interview stated he parked at the Farm Beauro building (actually the old cps building) I do not think this was a mistake on his part. IMO He did not want to utter the words "child protective services building" to LE ...either out of pure guilt or a connection to that building/agency he did not want to reveal or both.. This is possibly how Kathy Shank comes into the picture but this might be a stretch
3) LE states BOTH victims clothes were found a distance away from their bodies by a a water source. This would lead me to believe he had some sort of sexual contact with the victims and may have left DNA that has now been matched to him.
AS i stated in my earlier post I believe they have RA dead to rights guilty. They used the 40cal for probable cause to charge him. When it comes closer to trial I feel more substatnial evidence against him will come out. IE boot prints,his dna on victims, victims dna on his clothes.
