MONTREAL - The $100,000 reward for information on a Quebec girl missing since last summer is set to expire this weekend.

Cedrika Provencher vanished last July from near her home in Trois-Rivieres, Que.

Quebec provincial police have decided to return the $100,000 to the anonymous donors, saying the reward's usefulness has run its course.

Despite thousands of tips and leads, police have had no luck finding the girl.

The girl's father, Martin Provencher, says he's optimistic his daughter can still be found.

While police continue their investigation, Martin Provencher says he will continue to search for Cedrika himself until she's found.
