The search for German woman Monika Billen cycled back to the tourism precinct. Initially reported as last seen on New Year's Day, she went to Emily Gap and the following day got a lift back to Alice Springs. Then she disappeared on January 2, a few hundred meters from her hotel in Barrett Drive. The full scale police search is continuing. ERWIN CHLANDA reports.
