The reward for information leading to the whereabouts of Jennifer Catcheway has increased to $7500, after a donation from the Assembly of Manitoba Chiefs Thursday.
The AMC, the Long Plains First Nation, and Manitoba Search and Rescue have each donated $2500 to the effort.
The 18-year-old Portage la Prairie woman has been missing since June 19 and officials say she could only survive without food for three weeks.
Search and rescue teams have used planes, boats, and dogs to search the area around her community.
The family believes Catcheway may have been seen at a house party in the area on Friday June 20.
Catcheway's family was expecting her home the night before, to celebrate her 18th birthday.
She called her family from Grand Rapids June 19 to say she was coming home with two male friends, one of whom was her cousin.
Police arrested two men for questioning, but released them without charges.
Police also spent a day searching in an area of brush near the Interlake town of Gypsumville.
Anyone with information is asked to call 777-0553.
