Raul Perez Zaragoza, 53, was shot and killed on November 28, 2014, inside his home on the 500 block of East Second Street in Rialto, California. Zaragoza was taken to a hospital but died of his injuries.

Authorities say no obvious motive has been identified and there is no evidence Zaragoza knew his attacker. The case remains unsolved and the suspect has not been publicly identified. Police have been following tips but have not announced any arrest or significant development.

Anyone with information about that evening or the vehicle seen fleeing is asked to contact investigators. Would anyone in Rialto that night be willing to share what they know?
