Craig "muMs" Grant, known for his role of Arnold 'Poet' Jackson on HBO's Oz, has died at the age of 52. The actor and writer died on Wednesday, a representative for Grant told PEOPLE in a statement.

"We are heartbroken over the loss of one of the most genuine, caring, loving souls we have ever had the pleasure of representing," the statement reads. "muMs was more than our client, he was our dear friend. We all just lost a phenomenal man."

According to his rep, Grant was filming a recurring role on Starz' Hightown in Wilmington, North Carolina, at the time of his death and was scheduled to travel to Atlanta to finish to wrap on a recurring arc on the BET+ series All the Queen's Men.
