KSAT: SAN ANTONIO – It’s been eight months since Derrick Jenkins last saw his mother. Thursday night, the 13-year-old got a surprise that made up for the time they spent apart. Lt. Col. Cotina Jenkins-Sellers just returned to San Antonio from Kuwait. With military-precision planning, she sneaked into Legacy Middle School on Thursday while Derrick was playing basketball. The coaches had arranged it so Derrick would shoot a free throw as his mother walked onto the court to surprise him.
