Annelise Schweickardt, a 68-year-old German citizen, was last seen at her Sarasota, Florida, home on April 9, 2003. She had lived in the United States since 2001 and kept her tourist visa current by traveling abroad at least once a year. Friends reported her missing after several weeks without contact.

Schweickardt had been renting a room to John Alan Mellquist and was in the process of evicting him when she disappeared. Mellquist told police she had left for a family emergency in Germany, but investigators later found his possession of her car, use of her credit cards, and forged checks in the months after her disappearance. A search of her home uncovered bloodstains and signs of a cleanup attempt. Schweickardt’s body has not been found, though authorities strongly suspect she was killed by Mellquist based on the circumstantial evidence.

If anyone knew Annelise, her movements in Sarasota in early April 2003, or has information about her whereabouts, please share what you know with investigators.
