My thought is that it has taken LE from July 17th until September 14th to basically verify RC's reported sighting. I think they are now working on what the other witness reported. I believe it is highly likely the girls left their bikes on the trail to walk back up to the skate park to meet a cute boy... if only to say hi or see if they could get the boys to notice them. If they had their bikes GMA could have recognized them. GMA could have specifically been looking for the girls riding their bikes. If she did not see the bikes she passed by. I don't think she would have turned south off of Gilbert onto Frans, Lake, Evans/Arbitus. She most likely, if traveling east, she would have turned left onto Grand Blvd. She did not think the girls would go to the lake, but she might have thought they would have gone to the skate park even though they were not supposed to ride that far. Maybe LE is getting ready to release information of where exactly the bikes were spotted (if it was the girls' bikes) and where they were eventually found.
