One of the divers who went to Uddevalla on Saturday was Monica Holmberg.
She had left Stockholm in the morning to dive for several hours in Bäveån along Junokajen - all to search for traces of the murdered 17-year-old Wilma Andersson.
- We want to try to find something that can help the family get an end.
Anything at all that can lead to them getting peace, says Monica Holmberg.
Divers from all over the country
Nearly 80 divers from across the country were involved in the search during the day.
- Rather to do a great thing than that ten at a time come here and need to do it again and again. If she is here now, we should be able to find her, says Monica Holmberg.
