In my opinion RA is guilty of the murders and will be found guilty in a court of law.I believe he acted alone during the murders and was alone with the 2 victims at scene of the murders....that being said here are some thoughts
1) IMO RA went to LE first (Friendly conservation officer?) first to let them know he was on the bridge but did not see the girls.He did this because he knew the other 3 girls saw him leaving the area and would surely tell LE of his presnece on the bridge that day.
His report went unnoticed for several different reasons. One being in the very early stages of the investigation the initial description of the suspect looked nothing like RA.Another is The " local friendly" LE he made his "helpfull tip" too never thought twice about it ,as his statement like others on the bridge that day was originally OFFERED in good faith from a concerned local citizens trying to help LE.The "friendly" LE officer probably had no knowledge of the 40call bullit found as he was not "in the know" on that piece of information let aloine if RA owned a 40cal. Add KK into the mix and all the lies he brought to the investigation and you have a perfect storm for RA to miracuously fly under the radar.
The report RA made was never looked at until recently by new investigators (Kathy Shank?) who found the old "tipster" report and then made the connection with bullit/gun ownership and the fat RA was on the bridge that day but other then the report she was looking at ,there was no mention of RA anywhere. Once that connection was made everything else fell into place:the gun,dna,boot prints,blood...etc. IMO They never looked at RA at all , let alone as a suspect until this newest connection was made. He got very lucky to get away with it for so long.
I Would not put blame on LE but rather bad timing and back luck .
2) IMO RA is pleading not guilty and claiming innocence because he is a sick F$#@K who wants to play this game for years and years to come. The type of beast to claim innocence to his dying day for his own sick pleasure. I am sure We will hear about all sorts of possible suspects from his lawyers when this trial starts ..but..the only person who is going to be directly connected by scientific evidence is RA.
3) Instead of dragging LE and grasping at straws why this took so long , I am going to be thankful this animals day in court is coming . All of our questions will be answered in the coming months...we waited 5 years whats a few more months.
