because he stayed in the background, many people never knew that he was deeply involved, too." King was involved in the Selma demonstrations (Bloody Sunday) and participated in the Poor People's Campaign: "Operation Food Basket and the sanitation living wage campaign, March in Washington and many more". King tended to stay in his brother's shadow, and many people never even knew that Martin Luther King Jr. had a brother. He supported his brother throughout the movement but never took the limelight away from him. King's side office at Zion Baptist Church in Louisville, Kentucky was bombed. King often traveled with his brother, and was in Memphis on April 4, 1968, when his brother was shot dead. King was in the room directly beneath Martin's at the Lorraine Hotel when the gun blast went off, and when he saw his brother lying mortally wounded, he had to be restrained by others, due to the shock and overwhelming emotion he was experiencing. Later life For the last part of his life, he suffered from alcoholism and depression. In 1965, King moved to Louisville, Kentucky, where he became pastor at Zion Baptist Church. While there, King continued to fight for civil rights and was successful in a 1968 campaign for an open housing ordinance which is today a component of the Fair Housing Act of 1968. After his brother's assassination in April 1968, there was speculation that King might become the president of the Southern Christian Leadership Conference (SCLC). King, however, made no effort to assume his deceased brother's role, although he did continue to be active in the Poor People's Campaign and in other work on behalf of SCLC. After Martin's death, King returned to Ebenezer Baptist Church, where, in September 1968, he was installed as co-pastor. He was praised by his father as "an able preacher, a concerned, loving pastor". Death On July 21, 1969, nine days before his 39th birthday, King was found dead in the swimming pool at his home. The cause of his death was listed as an accidental drowning. However, it is likely that the stress of his brother's high-profile activist work and the trauma of his assassination exacerbated A.D.'s heart problems (a rumor disclaimed by his wife Naomi Ruth Barber King), of which there was a family history: three of A.D.'s children later died of heart attacks—Alfred Jr. in 1986, Darlene at age 20 in 1976,
