I think they have been building a solid case so far, imo. Brick by brick. They illustrated why Bridge Guy is the killer.
And now they are showing us that Bridge Guy is actually RA. RA puts himself there on the bridge at the same time as BG, and admits to be wearing the same clothes as BG. His jeans even fit exactly like BG's, with the material clumped up at th bottom because of his short legs.
RA never said anything about seeing another male there on the bridge while he was there, or even one on the trail. And there was no male that came forward and described seeing RA there.
The ONLY man on the bridge was RA. His car was backed in at the CPS building, which is apparently the way he likes to park.
The girls said on the video that BG had a gun. And then we find out that RA has a gun just like the on that ejected a cartridge found between the victim's bodies. So he was dressed exactly like Bridge Guy, has short legs like BG, was on the bridge at the same time, a car like his was parked nearby, and he owned the same type of gun as BG.
If we add 60+ confessions to the above 'coincidences' it makes me lean GUILTY.
