Luis Rene Murrufo, a 36-year-old Hispanic man from Tyler, Texas, was found dead on June 30, 2019. Officers responding to a reported shooting at a residence in the 1500 block of County Road 328 West discovered Murrufo inside a vehicle parked in the yard. He had suffered a fatal stab wound; the autopsy later showed 22 stab wounds to the head, neck, chest, back and left arm. Another person at the scene had a gunshot wound and was taken to the hospital with non-life-threatening injuries.

Two days later, on July 2, 2019, 41-year-old Humberto Leal was arrested and charged with murder in Murrufo’s death. Leal was shot in the lower abdomen and treated at UT Health East Texas; he initially told investigators he had stabbed Murrufo four times while Murrufo was standing and claimed self-defense, but investigators found discrepancies between that account and the evidence, including the autopsy findings.

Were there witnesses or local information about what led to the argument between the two men earlier that day or to their prior altercation six months before?
