(AJC) — The Rev. Howard Creecy Jr., a prominent Atlanta minister who was elected president of the Southern Christian Leadership Conference earlier this year, died suddenly Thursday, the civil rights organization said. Although the cause of death has not been determined, Creecy’s family suspects the pastor of the Olivet Church inFayette County died of an apparent heart attack at his Atlanta home around 12:30 a.m., according to the SCLC. The group said an autopsy has been commissioned. Isaac Newton Farris Jr., a nephew of SCLC co-founder the Rev. Martin Luther King Jr., has been named interim president, the organization said.
