Rae Sremmurd‘s younger half-brother Michael Sullivan is in custody as a person of interest following the fatal shooting of their stepfather Floyd Sullivan, 62.
The stepdad of the hip-hop duo – brothers Slim Jxmmi and Swae Lee – helped raise them since they were young, TMZ reports.
Floyd died after the shooting on Monday night (January 6) in Mississippi.
Tupelo PD reports that police officers were dispatched to a home, where they discovered a man who had died on the scene from at least a couple of gunshot wounds.
Police are holding Michael, 19, for psychiatric evaluation. They say no one else is being sought after in connection with the shooting.
Floyd also has a son, Floyd Jr., from a previous relationship.
