Michael Sullivan was initially taken into custody for a psychiatric evaluation after police in Tupelo, Mississippi found his dad, Floyd Sullivan, shot dead at the family home on Monday night, January 6, 2020.
At the time, the 19 year old was named as a person of interest in the case, but he was released from hospital on Tuesday and placed under arrest for murder by officers at the Lee County Sheriff’s Department.
Floyd, 62, had helped to raise the Rae Sremmurd siblings with their mother, Bernadette Walker, and the tragic turn of events has left the stars devastated.
"Both Slim and Swae Lee are deeply saddened by the death of their stepfather, but both are thankful for the love and support they had during their upbringing," the duo's spokesman, Juel Stanley, shares in a statement.
"They ask that people respect their privacy during this time of grief and mourning."
Swae, real name Khalif Brown, has also taken to Twitter to express his shock at the news.
After tweeting out four broken heart emojis, he posted, "I pray this world let's (sic) me keep some compassion."
