I had a little research into this last night.
Marty would have been 13 at around 1973-74.
The address I found for Victory Lanes Bowling was Victory Lanes Family Bowling Center 2311 Fort Benning Rd Columbus, GA.
If that address is correct, then this map shows that whilst the bowling center isnt backing onto the river, it is within driving distance, but who is driving at 13?

So I'm wondering if the disappearance happened at a later time.
Some horrible language is used in this post, so I havent posted the image here. I will say that he mentions this is the "First time", so were there more?
With not much to go on I had a search using some of the sites for GA listed on here over the 70's (Remains and missing) and though I didnt find anything in the river specifically (which having looked at some videos, is very fast flowing, and google said it flows SW) I did find something else 2 bodies found in coal train carts.
10th June 1978 - One of these people had some interesting descriptors...long fingernails, curled eyelashes and bikini underwear.

Apologies if some of my assumptions here are a bit of a reach, this is my first case related post, i'm not from that area.
