Two people are in police custody after a rookie police officer and a bystander were killed in a shooting at a dance at the Gila River Indian Reservation in Arizona early Saturday, authorities said.
The FBI is investigating how Officer Joshua Briese, who was still undergoing field training, was shot and killed. The bureau confirmed Sunday that two suspects — an adult and a juvenile whose names were not released — were in custody and receiving medical care.
Another police officer was shot and in "serious but stable" condition, police said. Four others were also shot, police said, one of whom has died. The rest are being treated at local hospitals; their conditions are not known.
"Our hearts and prayers are with these police officers, their families, and everyone impacted by this tragic incident," the FBI said in a statement.
The Gila River Indian River Community Council said on its Facebook page that it held a meeting Saturday to call a moratorium on dances.
"It was scary. I was scared when I heard the gunshots. We all dropped to the ground," a person who was at the dance, who asked not to be named, told NBC affiliate KPNX of Phoenix.
Police forces, lawmakers and community groups all paid tribute to Briese. “Our hearts and prayers are with these police officers, their families, and everyone impacted by this tragic incident,” Gila River police said on Facebook.
Stephen Roe Lewis, governor of the Gila River Indian Community, said in a news release: “I know I speak for our entire Community when I say that we grieve for our fallen and injured police officers and every Community member touched by such tragic violence. Nothing cuts deeper than a life cut short.”
Briese's father was Dave Briese, a Yellowstone County sheriff's deputy who died in a car crash in 2006, said a post on the Yellowstone County Sheriff's Office Facebook page.
"Knowing Dave & Josh are together again, both left this world serving their community and doing what they loved," the post read.
The Arizona Trooper's Fraternal Order of Police Lodge 32 said on X that the other officer who was shot was Briese’s field training officer.
