Authorities in Minnesota reportedly arrested a 12-year-old boy early Wednesday in connection with a deadly drug-related ambush last month in a park in Omaha, Neb.

The boy, along with two other boys — Jamar Milton, 17, and Shuntayvious Primes-Willis, 15 — allegedly planned to rob two men they lured to Miller Park on June 29 on the premise they wanted to do a marijuana deal, a Douglas County prosecutor told the Omaha World-Herald.

Milton and Primes-Willis were arrested Monday, Fox 6 reported. Both teens were being held without bail and charged as adults with first-degree murder. Jamar Milton and the 12-year-old are brothers.

Douglas County Prosecutor Jim Mastellar said the boys, who police say have gang ties, flashed guns during their meeting with the two men, identified as Charles Fisher, 30, and Jamymell Ray, 31.

Primes-Willis allegedly shot Fisher, wounding him, but it was unclear which of the boys shot and killed Ray, the newspaper reported. District Attorney Don Kleine said police found two guns at the scene, and were searching for a third.
