This is from doe network:
"The rifle was sold in Fort Wayne, Indiana in 1939, but no further tracing of the gun's ownership could be found. The brass key hasn't been matched to any location. The dental work has yielded no matches."
It was also in a few newspaper clippings.
I'm going to review why I think magnum was correct. Starting with macro information and working towards fine details.
1. The homicide rate was about 4 per 100k in 1957. A very small group to be part of to begin with.
2. Mr bones was over 6'1 and so was Connor. Another statistically small group to be part of.
3. Two men saw forsyth shoot Connor in the head, with a rifle.
4. The (bones) rifle original point of wholesale was ft Wayne Indiana, where Forsythe lived for a time. Very close to lima.
5. Forsythe was seen almost exactly at the mid point between bedford and Lima. The person that saw him and his wife cleaning blood out of his car. That person went so far as to write the plate # in a shed door. Which was removed and used in his trial.
6. The wounds to Mr bones, are exactly what one would expect Connor to have, based on witness testimony.
7. The time of death for Mr. Bones lines up with Connor.
8. (Incidental) a lot of illegal transactions were known to take place in small cities in western NY and PA (Olean, Bradford, Elmira & more) as its the half way point between East Coast cities and large mid west cities) given Forsythes history, I think it's very possible he was familiar with the general area.
9. The time between when Forsythe shot Connor, and when he rolled back into town, is enough of a window to comfortably make the trip to bedford and back. We also know for a fact, he was at least half way. Without the body.
The only possibility are:
He dumped the body west Cadiz oh, and went further east to clean evidence from the car. Then circled back.
He dumped the body further east than Cadiz, and stopped there to clean the evidence.
I think the 2nd I'd more likley.
Also, I think we can assume it's better to dump a body at night. That said, he dumps Connor in the middle of the night, and at first light, he is in cadiz, 4 hours away. Which lines up perfectly if he unloaded him at 2-3 am. It is also damn near a straight line between lima, cadiz, and bedford.
* also no other body has been found between lima and cadiz.
Thanks for indulging me... lol
In the end I think this is still open because no one in authority cares.
As evidenced by the way they treated magnum PE.
