Jarrell Milton, a fugitive wanted on murder charges, was arrested in Minneapolis and is now in the custody of the US Marshals Service, the Omaha World-Herald reports.
Reports quoting police sources say Milton, his 17-year-old brother Jamar, and a 15-year-old, Shuntayvious Primes-Willis, shot two men, killing one in what seems like a drug deal gone sour.
One of the men, 31-year-old Jamymell Ray, died.
The World-Herald reports that the gang had arranged a meeting for a marijuana deal where the shooting took place.
All three of the suspects had weapons and prosecutors want to charge all of them with first-degree murder as adults.
"It's unbelievable when you think of somebody who's 12 years old, seventh grade or sixth grade, and being charged with murder for having a gun—approaching somebody and using that firearm with two other people that also had firearms," a prosecutor told WOWT.
"It's even impossible to imagine that it's even a possibility."
However, the law may not allow them to charge the 12-year-old as an adult.
