As your link above mentions, Darrell Tomlinson was the hospital worker who said he found it.
Questions about planting a bullet:
How did the "planters" know to plant a bullet that was only "slightly" damaged if it was to have gone through at least one person the President? And no one else?
How did the "planters" know they could plant that bullet before they knew how many other bullets would be recovered? How could they have known that CE 399 would not be the "extra bullet" that would blow the whole plot? That it wouldn't reveal another shooter?
How did the "planters" know what general size, shape and condition the bullet could be - had to be - before the actual bullets would be found? Before Connally was operated on? What if a large part of the bullet that hit JFK was found in JFK's neck or upper back, a piece or fragment that was too big to have come from CE 399? What if a large piece was lodged in Connally? What if it had gone through JFK and hit the interior of the car? Or another passenger?
How did the "planters" know before the assassination they could do all of this, i.e, plant that specific bullet with its unique qualities, afterwards? That their actions wouldn't reveal the plot?
And, if CE 399 isn't the bullet that went through JFK, then where IS that bullet? Did it disappear?

Whoever planted that bullet was not concerned with what it was supposed to have inflicted. A bullet that could be definitely linked to the suspected rifle was what was desired.

Same as above. Only that bullet would be found. The fix was in. This is why the body of the president was Shanghai-ed back to DC ASAP.

Asking the same basic question redundantly. The president's
dead body received more 'protection' than when he was alive!

The fix was in! Good Grief Charlie Brown!

No. For all we know there are still bullets in the president's body. They put him in the ground ASAP by orders of LBJ.
