The deceased youths were a 17-year-old boy and a 16-year-old girl.
They were out driving an A-tractor when they collided head-on with a truck on road 44 between Lidköping and Grästorp, the incident occurred during the night of Thursday last week.
- This particular thing about being together and remembering together, because this is a moment of remembrance for these two young people, says vicar Jana Pollari.
