Forensic evidence at the trial strongly suggests that McKnight's killer's story about the shooting is not true.

Ronald Gasser was allowed to go home the night he confessed to fatally shooting former NFL player Joe McKnight following a road rage confrontation at a Terrytown intersection because investigators had very little information to contradict Gasser's statements of self-defense, Jefferson Parish Sheriff's Office homicide commander Lt. Donald Meunier told jurors Wednesday (Jan. 24.)
Meunier said the following day's autopsy results, which indicated a lack of "stippling," or gunpowder residue, on McKnight's body, cast doubt on Gasser's version of what had transpired at the intersection of Behrman Highway and Holmes Boulevard.
"It was a red flag," Meunier said under questioning by Assistant District Attorney Shannon Swain.
