One suspect was arrested on murder charges for shooting and killing a Dutch soldier who was training in Indiana and wounding two others, the Indianapolis Police Department said.
Shamar Duncan, 22, was arrested on Tuesday afternoon.
He is accused of shooting and killing 26-year-old Simmie Poetsema, a member of the Dutch Commando Corps, on Saturday around 3:30 a.m. outside Poetsema's hotel in downtown Indianapolis.
Two other Dutch soldiers also suffered nonlife-threatening gunshot wounds.
The victims were in Indiana for training at the Muscatatuck Urban Training Center, a military base about 70 miles southeast of Indianapolis.
Law enforcement has remained tight-lipped about what led to the shooting outside a Hampton Inn where the soldiers were staying, but Indianapolis Mayor Joe Hogsett said there was a disturbance at a bar.
"As I understand it, there was a scuffle, a kerfuffle, at a bar and the Dutch guardsmen had returned back to their hotel. What they were doing outside, I'm not altogether sure, but I'm told the alleged perpetrators did a drive-by shooting and ultimately three were victimized by that shooting," Hogsett said Monday.
