True. She saw a man who might be Richard Allen on the bridge at the same time that Richard Allen said he was on the bridge looking at a fish. She thought he was on the first platform, he was vague.
She turned around and walked to her car. We don't know whether the man on the bridge followed her. We do know that as she was walking to her car, she saw Libby and Abby walking towards the bridge. Bridge guy and the girls were between her and bridge. The girls were on the South end of the Monon bridge when a man, moving with purpose, was right behind Abby.
I think eye witness testimony that corresponds with Richard Allen's testimony is more important than trail descriptions. The witness places the girls on the bridge trail at the same time as the man she saw on the bridge. RA admitted that he was there, looking at stock market reports and fish.
One witness connects Richard Allen to the bridge near the time that the girls are on the bridge. Other witnesses might have seen Richard Allen on the trails in the form of bridge guy until the 3:57 muddy bloody sighting.
His wife is not a witness, but I would like to hear what happened when he arrived home that day. He must have been covered with blood, from head to toe. Libby put up a good fight.
