Edward Gallagher was a decorated 19-year Navy veteran on his eighth tour of duty. And military prosecutors say that while serving in Mosul, Iraq, in 2017, he snapped.
Gallagher plans to plead not guilty to multiple charges of war crimes at his arraignment hearing Friday at Naval Base San Diego, attorney Phillip Stackhouse told NPR.
Prosecutors say the Navy SEAL fired indiscriminately into Iraqi crowds. They say he shot an elderly man carting a water jug in Mosul, as well as a girl walking along a riverbank there, the AP reported. They also say Gallagher fatally stabbed an injured teenage Islamic State prisoner while another U.S. medic was working to save his life.
"I got him with my hunting knife"
According to the charge sheet, Gallagher is accused of committing premeditated murder against the wounded teen by "stabbing him in the neck and body with a knife." At a November preliminary hearing, prosecutors elaborated: After Iraqis called in an airstrike on a building, they captured a wounded ISIS fighter who was about 15 years old, Naval Criminal Investigative Service Special Agent Joe Warpinski told the court, according to the military trade publication Task & Purpose. The Iraqis turned the fighter over to the Navy SEALs, and medics began treating him for shrapnel in his left leg and difficulty breathing.
While one SEAL medic was treating the teen, Navy investigators say Gallagher walked up without saying a word, took out a handmade knife, and stabbed the teen several times in the head and neck, the medic told military investigators, according to The New York Times. Afterward, Gallagher posed for photos next to the body, prosecutors said.
Gallagher then completed his re-enlistment ceremony next to the body, prosecutors allege. Later, Gallagher allegedly texted one of the photos to a fellow SEAL, along with the text: "I got him with my hunting knife."
Prosecutors say there were three eyewitnesses, according to Task & Purpose. Gallagher's attorney told the court the teen died from injuries from the airstrike, despite Gallagher's attempt to save him, the AP reported.
One month after that alleged incident, while Gallagher was stationed with a sniper rifle in a tower near the Tigris River, prosecutors say he allegedly shot and wounded an elderly Iraqi citizen walking along a road and carrying a water jug. In July 2017, he allegedly shot a young girl from the same location. Some SEALs were so concerned about his actions, investigators said, that they tampered with his rifle to make it less accurate. They would even fire warning shots to clear areas of civilians, investigators said.
The Navy arrested Gallagher in September to stop him from intimidating witnesses, prosecutors said. During the November hearing, Navy prosecutor Chris Czaplak said Gallagher had damaged the reputation of the United States, the Times reported.
"Does the public still believe we are the good guys, because Chief Gallagher decided to act like the monster the terrorists accuse us of being?" Czaplak said. "He handed ISIS propaganda manna from heaven. His actions are everything ISIS says we are."
If convicted, Gallagher faces up to life in prison.
"This is not who Eddie is," his wife, Andrea Gallagher, told the Times in November. "He is a lifesaver. He is that guy who runs into the burning building when other people are running out."
Stackhouse previously told NBC that witnesses provided conflicting statements, and that "if we are allowed to present our case, at the end of the day, Eddie will be acquitted of the charges." In November Stackhouse told the Times that the SEALs who made the allegations against Gallagher were disgruntled because they couldn't meet his demanding standards. "I promise you, we will call many more SEALs who will say none of this ever happened," Stackhouse said.
In December, Stackhouse told Fox News he would "very much appreciate the president taking a look at Eddie Gallagher's case."
