This is the WC visualization of the JFK head shot. Did the slug, or a fragment thereof, then strike the curb near the feet of Tague?
ME: Is it plausible that the bullet that hit JFK in the back of the head fragmented and that a piece of it struck the curb near James Tague?GROK: Yes, it is plausible—both ballistically and based on the physical evidence—that the bullet striking JFK in the back of the head fragmented extensively, with a small piece (or pieces) continuing forward to strike the curb near James Tague and send concrete debris into his face. This is not the Warren Commission's official conclusion, but it aligns with known facts about the ammunition, wound ballistics, trajectories, and curb damage. Here's why, based on the documented evidence.
The fatal head shot (Zapruder frame 313, the third shot per the Warren Commission) was fired from a 6.5×52mm Mannlicher-Carcano full-metal-jacketed (FMJ) bullet from the Texas School Book Depository sixth-floor window. At that range (~265 feet / ~90 yards from the rifle), the bullet struck the rear of JFK's skull, fragmented dramatically on impact with bone, and caused the massive head wound seen in the Zapruder film, autopsy, and ballistics tests.
Two large fragments from this bullet were recovered in the front of the limousine (CE 567, the nose portion ~44.6 grains; CE 569, the base portion ~21 grains). These were matched ballistically to Oswald's rifle.
Roughly 90+ grains of the original ~160-grain bullet were unaccounted for (including smaller lead particles in the car and JFK's brain). Wound-ballistics experts, including Larry Sturdivan (who consulted for the Warren Commission and HSCA), noted that much of this missing mass sprayed forward after the skull impact.
At the moment of the head shot, the presidential limousine was on Elm Street, with the triple underpass (and Tague's position on the south curb/sidewalk nearby) further ahead and downrange. Tague was standing ~178 yards from the sniper's window overall, meaning the forward distance a fragment would need to travel from JFK's head to the curb mark was on the order of ~80–90 yards. One small fragment from the head shot already cracked the limousine windshield from the inside (a very short distance), demonstrating the forward spray of debris.
The curb mark itself (a fresh chip/scar on the south curb of Elm Street near the underpass, about 20–25 feet from Tague) showed:
A lead smear/residue consistent with the lead core of the assassination ammunition (per FBI spectrographic analysis after the curb section was removed in 1964).
No embedded copper jacket material.
This is exactly what you'd expect from a fragmented bullet's lead core (as from the head shot) rather than an intact FMJ bullet glancing off (as the Warren Commission attributed to the "missed" first shot). An intact Carcano bullet would likely have left copper traces.
Tague described the impact as a sting on his right cheek from flying concrete/debris during the shooting sequence. He initially linked it to the second or third shot (later pressed to say the second). Witnesses and police noted the fresh curb damage immediately after.
Ballistics analyses have explicitly considered this scenario plausible. For example:
Sturdivan and others observed that the missing head-bullet mass cleared the windshield area and continued in the general direction of Tague.
Forward trajectory extensions from the head wound align with the curb location.
A small, low-velocity lead fragment (with reduced but still sufficient energy after skull impact) could easily produce the minor, superficial injury and curb chip observed—far more consistent than some convoluted ricochet paths proposed for the "missed" first shot.
The Warren Commission concluded the curb strike came from the first (missed) shot to account for three spent cartridges, the two major wounds (neck + head), and Tague's injury—leading to the single-bullet theory for the neck/Connally wounds. That remains the official lone-gunman narrative. However, nothing in the ballistics, fragment recovery, curb metallurgy, or trajectories rules out a head-shot fragment as the source. In fact, the evidence (especially the lead-only residue and forward spray) fits it well. Some detailed forensic reviews treat it as a reasonable alternative explanation for the "missing" bullet mass and Tague's wound.
In short: the Carcano bullet did fragment on the head shot, fragments did travel forward, and the curb damage/Tague injury is consistent with one reaching that spot. It is physically and forensically plausible, even if it wasn't the Commission's preferred account.
