PORTER, Ind. (AP) _ Indiana State Police say a search of a northwestern Indiana lake failed to turn up any evidence related to the disappearance last month of a Michigan doctor.

Police said Wednesday that the Jan. 23 search of Lake Charles in the town of Porter was part of an ongoing missing person's case involving Teleka Patrick of Kalamazoo. Her car was found abandoned by an Indiana trooper on Dec. 5 along I-94 and near the lake about 15 miles east of Gary.

Kalamazoo County Sheriff Richard Fuller has said Patrick told colleagues on Dec. 5 she was going to Chicago to visit a relative, but told another colleague she needed money and a ride to a nearby hotel.
