Quavo, Offset, and Cardi B’s posts have gone viral as they fondly remember Takeoff. Today, YRN Lingo, Takeoff’s brother, expressed his devastation in an open letter shared on Instagram.

“I honestly still can’t believe it,” wrote Lingo. “My big brother, my right hand, my other half, my literal twin. The one I could call upon anytime no matter what time, weather, situation you were in. You always made sure the family was straight, even when I didn’t need anything you always gave me something.”

YRN LINGO included several photos of the brothers growing up together. “I will see you again one day in heaven brother,” he wrote. “I’ll take care of Mama and Heaven down here. Take you fulfilled your purpose and more.”
