In December 1967, Jim Garrison released several pictures to the press which he believed proved that Kennedy was shot by a .45 caliber bullet.
Here is a UPI article on his theories:
Martin: You said a moment ago you would show us or tell us where you think that bullet was fired from, that the man was picking up from the grass there. Where do you think it was fired from?
Garrison: Well ... this is going to be the first time I've ever shown this, but we've gotten a little tired of hearing people like Earl Warren and Ramsey Clark, who ought to know better, saying repeatedly, that they've seen nothing new. Well, I'm going to show them something new. I think we just showed something new in this 45 caliber bullet because they've never mentioned it in 26 volumes. Right next to where the President was killed, just a little bit in front of where the President was killed, there is a sewer opening. Underneath Dealey Plaza there is a drainage system. Dealey Plaza used to have a bunch of houses and they were taken down to make the plaza. You have a surface drainage system with pipes through which men can crawl. The small ones are 15 inches wide, and the large ones are 30 inches wide. One of the assassins went, got his, made his exit through the subsurface drainage system. The one who went through the drainage system was the man who killed the President, who fired the 45 from the right by the side of the car and tore the President's head off. Now we went into the sewer one morning early in Dallas, got in in the dark, put the top down and we found a man fits in there very easily, we also found that after shooting from it it's easy to crawl under the street through the 15 inch pipe, when you're in a 30 inch sewer which leads out of Dealey Plaza to another part of the town. Entrance can be gained through two ways to the sewer area. I don't have a picture of the sewer here but you can take pictures in Dallas. Entrance can be gained directly above the sewer through a manhole.
Martin: Behind the grassy knoll?
Garrison: Well, no, that's another place but it can be entered above it by removing the cover of the manhole. You remember about an hour before there was a truck parked over the pavement which Julia Mercer saw but there can also be entrance behind the picket fence through a 3x3 grating down by the overpass which lifts up, you get in and you crawl through the 15 inch tunnel and you'll end up, there's only room for one man in the manhole but he can stand up in the manhole and when he gets in there he has a clear view of the occupants of a convertible from the chest up. In other [...] we didn't know until we put a man in there in the dark hours of the morning and waited until the sun came up and took photographs that you could see so clearly to the occupants inside the car, but you can.
Martin: All right, when you are inside the vantage point, from inside, where is that in relation to where the man was picking up something from the grassy areas across the street?
Garrison: Well, it's in a cattycorner kind of way. It's opposite, actually this is the proper way. The shooting was not due South it was towards the car as it approached diagonally slightly and if the line continues that's where the bullet ended up with the pieces of the President's head surrounding it. This is the bullet that disappeared as soon as the federal ... got its hands on it. The 45 caliber bullet from a handgun which was fired from the sewer.
Martin: Mr. Garrison, do you believe you have the identity of the person who was in that sewer?
Garrison: I would, I would not be accurate if I said I had the identity of the man in the sewer. We now have a number of names of individuals who apparently were at the operating level. I'd say four but there were so many more that I'd rather not speculate which one was standing where, so in all honesty, I'd have to say the identity of that particular man, no.
Here are a couple of pictures of the sewer opening (storm drain) on Elm Street:
That is how it looked back in March 2020 when I visited Dallas. Here is the picture Garrison released in 1967, and it doesn't appear there is a manhole cover on the storm drain:
The notion of a shot from the storm drain is just ridiculous. You would have about 2 seconds to fire a weapon and you would be aiming up at the limousine. If you go to my first post about a sewer shot, you will see some photographs that Garrison released from the storm drain.
Not to mention the problems of a person squeezing through those very narrow pipes.
Here is an entrance to the sewer system near the triple underpass.
