Twenty-one-year-old Antoinette Markus is also called "Annie." She was last seen Wednesday evening when she left a friend's home at Clark and Belmont in Chicago's Lakeview community.
Markus was taking public transportation to get back to the Oak Forest home she shares with her aunt, but she never arrived home.
Markus was wearing jean shorts, a teal sweater, plastic glasses and was carrying a tie-dye purse.
Police say her ATM card was used to take out over $300 from a location in the Loop.
Anyone with information on her whereabouts should call Oak Forest police.
