Arturo Muniz, 50, and his brother Rafael Muniz, 48, were fatally shot on December 14, 2014, on San Antonio’s West Side during an early morning incident. Their sister Laura Diaz says the brothers ran from their truck to intervene as good Samaritans in a fight between two men; one brother died at the scene and the other later at a hospital. Their mother was present and heard them express love for her in their final moments.

The shooter reportedly said he acted in self-defense, saying he retrieved a gun from his car and fired after a disturbance involving the victims. The San Antonio Police Department was investigating and no arrests had been reported; no suspect identities were disclosed.

Does anyone who was in that neighborhood that morning have information that could help investigators?
