Rapper Hakeem Robinson, better known by his stage name “Ksoo,” is heading to court Monday morning as jury selection begins in a case that’s drawn national attention—and stirred deep tensions in the city’s rap and gang communities.

The warrant obtained by News4Jax on Wednesday begins to unravel a tangled web of gang-related murders that has played out in Jacksonville over the past two years, all involving local hip-hop artists. Robinson is a well-known associate of Jacksonville rapper Yungeen Ace, whose real name is Kenyata Bullard.

McCormick was also linked to Jacksonville rapper Julio Foolio, who has an ongoing social media feud with Robinson.
