UTICA, N.Y. (AP) — On Wednesday, Nyah Mway finished middle school in the central New York city of Utica, where his family moved about a decade ago as refugees from Myanmar, relatives said.

By Friday night, the 13-year-old was fatally shot by police who’d tackled him to the ground after he allegedly pointed what turned out to be a BB gun at them during a foot chase.

Struggling to comprehend his death, his anguished relatives and outraged members of their immigrant community called Sunday for justice for him and accountability for police.

“We came to the United States, finally, to get the education and to get the good jobs here” and hoping for a peaceful life after decades of strife and violence in Myanmar, said Lay Htoo, who identified himself as one of Nyah’s cousins.

But instead of celebrating the teen’s ascent to high school, his parents were waiting for medical examiners to release his body and wondering what would become of the officers.

“They want them to be in prison forever,” the cousin said in a phone interview.

As the state attorney general and the Utica Police Department investigate the shooting, Nyah’s relatives and other local members of Myanmar’s Karen ethnic minority said they planned to meet Sunday afternoon with Utica Mayor Michael P. Galime.

For now, the officers are on paid administrative leave.

According to police, Nyah and another 13-year-old boy were stopped Friday night because they fit descriptions of suspects in an armed robbery that had happened Thursday in the same area, and because one teen was jaywalking. The police department declined Sunday to release the armed robbery report and its suspect description, citing the ongoing investigation.

The body camera video shows an officer saying he needs to pat them down for any weapons. Then one of the teens — identified as Nyah — runs away, turns and appears to point a black item at them.

The officers believed it was a handgun, police said, but it was later determined to be a BB or pellet gun that closely resembled a Glock 17 Gen 5 handgun with a detachable magazine.
