Police Information Officer Sam Clemens says a Sioux Falls woman is charged in a weekend prostitution case that began when a police officer spotted an internet ad.

Clemens says 22 year old Margaret Lynn Ghost was supposed to be caring for two relatives, a 9-year-old boy and a 10 year-old girl.  The children were taken into protective custody.

Ghost is charged with prostitution and also drug charges for a spoon that allegedly had methamphetamine residue on it.
