Jackson, 42, was longtime friends with Floyd. They grew up 45 minutes apart, Jackson in the fading oil-refining town of Port Arthur, Tex., and Floyd in Houston’s Third Ward. When a mutual friend introduced them, their resemblance was so striking that Jackson and Floyd jokingly asked each other who the other’s father was. They called each other “Twin.” Jackson had recently shipped Floyd a new suit to wear at a job interview.
