Cousin of rapper Lil Durk and Hip Hop artist himself OTF Nunu was reportedly shot and killed yesterday afternoon (May 31) in South Side Chicago. OTF Nunu, whose given name is McArthur Swindle, was 21 years old and had plans to release a mixtape this summer tentatively titled Nuski Got Da Strap.

Just days ago, Lil Durk released a set of visuals featuring Nunu on the song “OC.”

According to the Chicago Sun-Times, Swindle’s shooting may have been gang-related. The rapper’s aunt, Sherri Swindle, told the Times that Nunu was not affiliated with any Chicago gangs and added that he was taking college courses in Joliet just outside of the city.

The shooting took place shortly after 3:00 p.m. when an unidentified suspect approached Swindle in his vehicle and began shooting.

Complex reports that Nunu was seated in a vehicle and tried to escape when the shooting occurred. Nunu apparently crashed his SUV into a window-front after sustaining multiple gunshot wounds.

Just hours prior to the shooting, Nunu posted an image to his Instagram account with the caption “Im on sum cool shit.”
