Hey guys. This is the first posting in the forum, but I have read up on every post thus far in each thread. Here is my shot at it.
The map you posted above is accurate, but.

The direction that this person was heading, if it were the white truck seen, takes him directly to the I-10 exit east. I used to live right off of St. Landry, only blocks away from where this happened. Usually, people only take a few routes with their bikes to get to congress. You either go through what the locals call the "St. Streets", you can take St. Landry all the way down, passed Blackham Coliseum to Cajundome Blvd (which is SKETCHY), or you can cut over to Johnston Street from St. Landry. I did the math using Google Maps Directions, and the only way plausible for him to pick her up assuming she is not in the bed of the truck at the time the picture was taken of the white truck making a left onto university, is if he made the left onto University. . and then made another left further down to take him into the St. Streets where he waited for Mickey to pass by. Then, he will still be easily accessible to go towards this exit after abducting her. Those are my two cents, and that is ONLY IF it is her bike in the basin. Also, that basin is common for murders or bodies to be dropped off. It's really sad
