Dina was last seen in Latexo, Texas on January 19, 2000. She went to the home of her ex-husband, Curtis Shoemake, to visit her children. Curtis said Dina left with an unknown individual in a dark green 1990s model Chevrolet extended cab truck with Texas license plates, leaving her own vehicle behind at Curtis's house. She has never been heard from again. Her live-in boyfriend reported her missing several hours later, after she didn't return home from the visit.

Investigators never believed Dina left of her own accord; prior to her disappearance, she had planted flowers in her yard, which is uncharacteristic of someone who planned to walk away from life. Authorities believe foul play may have been involved in Dina's case. They haven't identified any suspects in her disappearance; it remains unsolved.
