BEAUMONT, Texas — Shamsud-Din Jabbar’s high school friends knew him as “Sham” — a good student with a quiet disposition and a bright future. “It’s a complete surprise, a shock, to everyone,” Jabbar’s half-brother, Abdur-Rahim Jabbar IV, 24, said in an interview. “He was very grounded, reserved, quiet,” said Chris Pousson, who attended middle school and high school with Jabbar. Courtesy Abdur-Rahim Jabbar IVAfter he graduated in 2001, Jabbar sought to serve his country. “It set him straight,” Abdur-Rahim Jabbar said, referring to a period after high school when Jabbar was partying and had some minor run-ins with the law.
