Yvonne Martinez, 37, was last seen leaving the Okay Casino around 1:50 a.m. on October 11, 2003. Later that day a passerby found her body on County Road 136B, about 10 miles north of Española, New Mexico. She had been shot twice in the chest, and the scene showed she fought back.

That timeline is the key part of this case. Someone saw her leave the casino, and someone may have seen who she left with or who followed her out. In 2003, many casinos had cameras on the parking lot.

Her family is still waiting. If you were at the Okay Casino that night or know who Yvonne was with, please contact investigators. It's been a long time, but people do remember.
