I was training on Radar east; GRK Approach handed off Aircraft Y southbound at 12;000 feet whose path coincided with the descend via STAR. ZHU handed off Aircraft X descending via the arrival at 14000. Aircraft X descended in front of Aircraft Y with 500 feet and 1.8 miles I believe. The Collision Alert never went off and I didn't notice it until two days later when it was received by TARP [Traffic Analysis and Review Program].Do not let GRK approach send overflights through the arrival drop box that coincides with the STAR.
AUS Approach Controller reported an airborne conflict due to a VFR aircraft in the path of an IFR arrival on a descend via clearance.
