(CNN) – When the trial of a decorated Navy SEAL opened in a San Diego military courtroom Tuesday, prosecutors promised jurors would hear from witnesses who saw the special warfare operator plunge a knife into the neck of a wounded ISIS prisoner.
But by week’s end, one of the prosecution’s own witnesses dropped a bombshell, testifying that he was the one responsible for the ISIS fighter’s death, not Chief Petty Officer Eddie Gallagher.
It was an extraordinary twist in the court-martial’s opening days, but just one of many revelations. Other witnesses testified that during their deployment to the Iraqi city of Mosul in 2017, they saw Gallagher not only stab the young ISIS prisoner, but fire at non-combatants, including a young girl estimated to be between 12 and 14.
“The thing floating over our heads,” one SEAL testified, “was that our chief was killing civilians.”
Gallagher stands accused of multiple violations of military law, including murdering a prisoner, posing for a photo next to a corpse, shooting at non-combatants and intimidating SEALs who might report his behavior.
Gallagher has pleaded not guilty. If convicted of murder, he faces life in prison.
The case has caught the eye of President Donald Trump, who has expressed sympathy for Gallagher on Twitter and is reportedly mulling a pardon for the SEAL.
Gallagher’s defense attorney, Tim Parlatore, told the jury of seven men in his opening statement Tuesday that there was no credible physical evidence for the murder charge against his client. The witnesses, Parlatore said, all had “an admitted hatred towards Eddie.” He echoed those remarks later in the week, saying “the younger millennial SEALs” were targeting Gallagher because he was “old school.”
“This case is not about murder,” he said Tuesday. “It’s about mutiny.”
‘It’s just an ISIS dirtbag’
Prosecutors began calling witnesses Tuesday afternoon, starting with Officer Thomas MacNeil, a SEAL who served alongside Gallagher. Under immunity, MacNeil told he court he posed in a group photo with the body of the ISIS fighter Gallagher is accused of killing, but that he didn’t know the circumstances of the prisoner’s death at the time.
Later, Gallagher ordered anyone who had the photos to delete them, MacNeil said. Gallagher also got in his face and yelled, “If you take me down, I’ll take all of you down.”
Navy SEAL Special Operations Chief Craig Miller testified Wednesday that he saw Gallagher stab the ISIS prisoner “on the right side of his neck, toward the jugular vein.”
Miller — who admitted to posing in a group photo with the body — said he immediately reported the murder to his superior. Miller testified that Gallagher asked him, “Who’s not good with it?” Miller said he told Gallagher that he was not.
Former Navy SEAL Dylan Dille testified he saw Gallagher pose for individual and group photos with the body of the prisoner, who he described as a frail, weak and injured 12-year-old.
Dille said Gallagher later told him and the others, “I know you’re not alright with what happened, but it’s just an ISIS dirtbag. Next time if I get a prisoner, I’ll do this where you can’t see what happens.”
Witnesses: Gallagher fired at civilians
Dille also told the court that Gallagher shot at civilians who were not military targets.
During one such incident — in which he, Gallagher and others were on sniper duty — the SEALs saw two elderly men standing on a corner. Dille testified that he heard a rifle shot and that one man was hit, struggled and got away.
Dille saw a vapor trail from Gallagher’s position, Dille said, and heard Gallagher say over the radio, “Oh, I thought I missed.”
Gallagher also shot near two women wearing hijabs, Dille said, causing them to run.
The former SEAL conceded on cross-examination that he did not see Gallagher pull the trigger. He based his accusations on the vapor trail he saw emanating from Gallagher’s position, he said.
Later in the week, Dille’s testimony appeared to be corroborated by two more witnesses.
One of them, Dalton Tolbert, said he fired a warning shot at an old man during a sniper mission with Gallagher. As the old man ran away, Tolbert testified Friday, another sniper fired and the man fell.
He heard a voice that sounded like Gallagher’s say via the radio, “You guys missed but I got him,” Tolbert said.
Like Dille, Tolbert said during cross he did not see Gallagher fire the shot. He was also confronted by defense attorneys about messages he sent in a group chat with other SEALs shortly before the trial started, two of which said, “Somebody fire this p***y a** f*****g judge” and “This legal process is a joke.”
Tolbert said those text messages were written out of frustration.
Another witness, Joshua Vriens, testified he heard shots fired from Gallagher’s position during another sniper mission.
Vriens said he saw four girls between 12 and 14 years old through the scope of his rifle. Following the shot, Vriens said one of the girls clutched her stomach and fell down. Like the others, Vriens said he did not see Gallagher fire the shot.
Witness claims he killed ISIS detainee, not Gallagher
But the undeniable highlight of the trial’s first week came Thursday, when one witness turned the case on its head, claiming he was the one who killed the ISIS prisoner in question.
Special Warfare Operator 1st Class Corey Scott, a Navy SEAL medic, said he saw Gallagher stab the prisoner under the collarbone. He said he saw no blood.
But on cross-examination, Scott admitted he killed the prisoner. Someone had already performed a tracheotomy on the prisoner, creating a small incision in his neck and inserting a tube to help him breathe.
“I suffocated him,” Scott said. “I held my thumb over his trach tube until he asphyxiated.”
“Did Gallagher kill this ISIS terrorist?” a defense attorney asked.
“No,” Scott answered.
Scott suggested it was an act of compassion because he was concerned that the boy — a prisoner of the Iraqi forces — would be tortured by the Iraqis.
Scott had not admitted to asphyxiating the prisoner in previous interviews with investigators and the prosecution but was doing so now since he was testifying under immunity and couldn’t be prosecuted, he said. He added he had no desire to see Gallagher go to jail because Gallagher has a wife and family.
Later, outside court, defense attorney Parlatore told reporters, “Today the truth is starting to come out.”
“Today for the first time somebody went to one of these witnesses and actually asked the question, ‘What is the cause of death?'” Parlatore said, surrounded by Gallagher and his family. “And what we learned is Chief Gallagher is not guilty of murder.”
The defense made a motion to dismiss the case based on Scott’s testimony, but was denied.
A Navy spokesman said in a statement that the government would not drop the premeditated murder charge against Gallagher, saying, “the credibility of a witness is for the jury to decide.”
The trial is due to resume Monday morning, when the court expects to hear from Navy SEAL Master Chief Brian Alazzawi, as well as a digital forensics expert and some witnesses from the Naval Criminal Investigative Service, or NCIS.
