/**

Takeoff was the youngest member of Migos, which included Cardi B's husband Offset and musician Quavo. Takeoff was Quavo's nephew, and Offset was Takeoff's cousin. 

The three family members were reportedly raised together by Quavo's mother in Atlanta.

The Grammy-nominated group is known for "Bad and Boujee," "Walk It Talk It" and "MotorSport." 

Finner began the conference with a "human element," expressing how "very tough" it was to speak with Takeoff's mother following his death. 

"I spoke to this young man's mother just an hour ago, flew in here from out of town," he said. "I want everyone to understand the pain and suffering of a mother."
