Katie Elizabeth Wantz was 21 when she was last seen in Eureka, California, on October 28, 2001. She stood 5 feet 6 inches and weighed about 140–150 pounds, with brown hair, brown eyes and a tattoo of roses on her back. She was also known by the alias Katie Masterson.

Her disappearance followed a troubling period. Katie had been a witness to a fatal shooting in Eureka on October 6, 2001, and was later named as a suspect in that case; a warrant was issued for her arrest, though it is unclear whether that warrant remained active when she vanished. A friend reported her missing on November 12, 2001. She left behind young children and has not been located.

Anyone with information about Katie’s whereabouts is asked to contact the Eureka Police Department.
