Rueben Perez-Silva, 47, was shot to death inside a residence in Oklahoma City on June 21, 2009. Officers were called after reports of an altercation involving a firearm; when they arrived they found him critically wounded with multiple gunshot wounds and he was pronounced dead at the scene.

Early investigation reportedly treated the shooting as possibly arising from a domestic dispute and police identified at least one person of interest linked to the argument, yet there was no immediate arrest.

If anyone heard or saw anything that morning or has information about the household or people involved, please come forward to help bring answers for Rueben’s family.
