Posted By Zoe Barnett Good afternoon, I hope someone out there can help me...I'm sure you'll all recall the recent tragedy in which two teenage girls drowned on a river walking expedition. I'd like to get hold of any information on the rationale behind the decision not to prosecute anyone involved - I seem to recall that it was due to lack of evidence but would like to be sure. Can anyone please point me in the direction of any info? Many thanks.
