In the Northern Marianas, fifteen FBI staff are leaving Saipan after their extensive search for missing sisters Faloma and Maleina Luhk proved futile.
The staff, along with an expert tracking dog brought in last week, will return to their home base in Honolulu, Hawaii.
The FBI agents assigned in Guam and Saipan, as well as local police, will be left to handle the disappearance of 10-year-old Faloma and 9-year-old Maleina.
The Department of Public Safety will also move the Incident Command Post in Kagman, which coordinated the search for the missing sisters, to the DPS main headquarters in Susupe.
Today marks the fourth week since the Luhk sisters were reportedly last seen leaving their house in As Teo.
The reward money for information on the whereabouts of the missing sisters is now 50,000 US dollars.
