    Details of Disappearance

    Siems was last seen leaving his Jupiter, Florida home one June 7, 1990. He was on his way to visit relatives in Arkansas, but never arrived there. He has never been heard from again.

    Siems's vehicle, a gray four-door 1988 Pontiac Sunbird, was found off State Road 315 near Orange Springs, Florida in July 1990. Witnesses identified Aileen Wuornos as one of the women who crashed it and fled the scene before authorities could arrive. Her palm print was also found on the vehicle. A photograph of Wuornos is posted below this case summary. She confessed to murdering six men, although two others are suspected victims. Her former lesbian lover, who was inside Siems's car when it was wrecked, testified against her. Wuornos was convicted of murdering several men, including Siems. She was executed in 2002.

    Siems is a retired merchant seaman who worked part-time as a missionary in 1990. His remains have not been recovered, but foul play is suspected in his case due to the circumstances involved.
