Although most believe that Weiss did confront Long, some claim that he only punched Long.
Nurse Jewel O’Neal was one of those who helped treat the dying Long.

In a 1935 affidavit, she claimed that while treating Long's bruised lip, he told her "That's where he hit me."
Proponents of this theory claim that Long was caught in the cross fire as his bodyguards shot Weiss, and was hit by one of the bullets which ricocheted off the marble walls.

Francis Grevemberg, head of the Louisiana State Police in the 1950s, claimed in an affidavit that during a 1953 gambling raid, he heard three state troopers say that bodyguards Joe Messina and Murphy Roden opened fire on Weiss after he punched Long.
He also claimed that one of Long's former security guards told him that Weiss's gun was removed from his car and planted at the scene.
Grevemberg claims he was told not to investigate.
Delmas Sharp Jr., the son of one of Long's bodyguards, claimed that in 1951 his father brought him to a bar owned by Messina.
He stated that his father identified Messina as the man who killed Long.
Messina turned his back on his colleague but did not deny the claim.

In a 1986 book, Ed Reed claimed that two bullets, not one, were found in Long's body.
He relied on testimony from Long's mortician, who claimed that a doctor returned late at night to remove an additional bullet from Long's corpse.
This was not the only discrepancy.
Weiss’ brother, Tom Ed Weiss, who arrived at the scene an hour after the shooting, claimed that Weiss' car had been moved from where witnesses had seen it at the door of the Capitol and that his brother's gun had been removed from the glove compartment.
Additionally, the coroner did not find car keys in Weiss's pockets.

Weiss' son, Carl Weiss Jr. believed his father to be innocent: "I don't believe that he fired a fatal shot or indeed that he carried a gun into the state Capitol that night."
In a 1985 conversation with Long's son Russell, Weiss learned of the existence of his father's gun.
With James Starrs of George Washington University, Weiss located the gun in a New Orleans safe-deposit box, owned by Mabel Guerre Binnings, the daughter of Louis Guerre, the state's head of crime investigations in 1935.
After a legal battle, she gave up possession of the box in 1991.
It contained Weiss' .32 caliber automatic pistol, a .32 caliber bullet that had been fired and had a blunt tip from an impact, and photos of Long's clothing, showing a single bullet hole.
After firing a test bullet, State Police investigators concluded that the bullet was not fired by Weiss' gun.
However, it could not have been from one of the bodyguards as they carried a larger caliber.

As Weiss was never given an autopsy, his body was exhumed in 1991.
His remains were examined at the Smithsonian Institution's Museum of Natural History.
Although nearly all soft-tissue had decomposed, pathologists were able to study his damaged bones.
They concluded that at least 24 bullets struck Weiss, conflicting with eyewitness accounts of at least 60.
This discrepancy is likely due to most bullets passing through soft-tissue and missing Weiss' bones.
They were also able to determine the angle of impact of each bullet: Weiss was shot front the front 7 times, thrice from the right, twice from the left, and 12 times from behind.
This indicates that Weiss was killed in an erratic crossfire.
A .38 calibre slug was found in Weiss' skull, having entered below his left eye.
According to ballistics expert Lucien C. Haag, a bullet of this size should have had enough energy to exit the skull.
He claimed that this lack of force was indicative of it passing through another body.
It is believed that this bullet passed through Weiss' arm: suit fiber was attached to the bullet and there was damage to bones in Weiss' arms.
Starrs claims that this suggests that Weiss was in a "defensive posture", with arms raised before him.

After the assassination, the MONY Life Insurance Co. dispatched company investigator K. B. Ponder to validate the nature of Long's death.
His 1935 report concluded:
