Transcript for Stunning twist in Navy SEAL trial
developments, we will bring them to you. Next tonight, the war crimes trial of a former Navy S.E.A.L. Accused of murders a captured ISIS fighter. A fellow S.E.A.L. Taking the stand, saying he was the one that killed the prisoner. Here's ABC's will Carr. Reporter: Decorated Navy S.E.A.L. Edward Gallagher was upbeat this morning, just before a bombshell exploded in his murder trial. One of his former team members took the stand and testified that he killed the wounded teenage ISIS fighter, seen in this Iraqi TV video, not Gallagher. Prosecutors have accused Gallagher, a sniper and a medic, of war crimes, including premeditated murder. Today, they called special operator first class Corey Scott as a witness for their case. Scott told the court he saw Gallagher take out his knife and plunge it into the wounded prisoner. But then Scott, who is a medic, as well, and who has immunity in exchange for his testimony, said that he, not Gallagher, killed the teen by plugging his airway, claiming he acted to save the prisoner from being tortured by Iraqi forces. "I knew he was going to die anyway," Scott said. Caught offguard, the lead prosecutor raised his voice, accusing their witness of changing his story and lying to protect his fellow S.E.A.L. Scott later testified, "Gallagher's got a wife and family. I don't think he should be spending his life in prison." Gallagher's defense attorney wloshgs has maintained that the charges were brought by disgruntled S.E.A.L.S, pouncing, saying, "Did chief Gallagher kill this terrorist?" "No," Scott replied. Let's get will Carr tonight. And you say this Navy S.E.A.L. Who testified today had been granted immunity. Does he face possible charges? Reporter: Well, that means he cannot be charged with murder, but he could still face a perjury charge. Part of the S.E.A.L.S creed is, my word is my bond. Tonight, that S.E.A.L. Says that he's the one who killed that teenager, not his boss, who is on trial. David? Really something in court today. Will, thank you.
