In Martin Luther King III's statement, he said, "The sudden shock is devastating. It is hard to have the right words at a moment like this" (via CNN). He then asked for prayers for his family and, more specifically, Dexter Scott King's wife, Leah Weber.

Dexter honored his parents' legacies by protecting them. The King Center wrote, "He devoted his life to the continued perpetuation of his father's legacy and the protection of the intellectual property (IP) his father left behind. ... Becoming well versed in intellectual property law, and its management and licensing was the result of his dedication to the delegated task and the memory of both his father and mother" (via X). 

Dexter's physical likeness matched that of his father. According to IMDb, Dexter voiced the 34-year-old version of his father in 1999's "Our Friend, Martin" special and brought him to life in live-action format for the 2002 film "The Rosa Parks Story," starring honorary Oscar-winner Angela Bassett as Parks. Although Dexter considered an acting career after that role, he instead focused on his other endeavors.
