Marlon Gomez, better known by fans as EMG Santana, was gunned down at the Mangum Oaks apartment complex at 4702 Mangum on July 30.
Investigators said there was some sort of argument before gunfire erupted at the apartments.
Witnesses told police they heard several gunshots before two unknown men fled the scene in a red hatch-back style vehicle, possibly a Ford Taurus X SUV.
Investigators describe one of those suspects as a black male in his 20s or 30s, 5'10" to 6' tall with a slim to medium build.
The rapper died from multiple gunshot wounds, according to police.
