Oklahoma, 1997: Kirsten Hatfield vanished from her home in the middle of the night. When her mother came to her room in the morning, Kirsten was simply gone. There was blood found on the windowsill, and a pair of her underwear were in the yard.
Hatfield was never seen again, but 18 years after her disappearance, DNA from the blood found was linked to neighbor Anthony Joseph Palma (56). He was arrested in October 2015 and charged.
Her family is hopeful that her body will one day be recovered.
