Andrews' practice was in the Acres Homes area, an impoverished African-American neighborhood in northwest Houston. There, he helped form the Acres Homes Citizen Council, which gave a voice to the community, and provided scholarships for needy students.
"He was the great leader of the community," Williams said.
Five years after his father's death, Murray, who also attended the same medical school as his father -- Meharry Medical College in Nashville, Tenn. -- opened his Houston practice, the Acres Home Heart and Vascular Institute, as something of a tribute to his father.
Williams credits Murray for saving his life. While on a trip to Las Vegas, where Murray also lives and practices medicine, Williams experienced chest pain. He said Murray performed surgery, putting several stents in his heart, and saved his life.
Williams is equally surprised to learn that Murray is at the center of an investigation into Jackson's death.
"Hell, he won't give me medicine," he said. "He doesn't believe in giving you a lot of pills. I don't believe he was raised to believe in that."
