Your decision

You've reviewed the material available to you. Now decide what you make of Fletcher's account and what further enquiries you would recommend.

Steve's Tips

  • Be clear about exactly what you've been asked to establish.
  • Take your time with the documents. Small details can make a big difference.
  • Look for information that supports Fletcher's account as well as information that might contradict it.
  • One of the most helpful exercises in an investigation with multiple sources of information is developing a timeline of events.
  • Think about what further enquiries could help establish the truth and what you would hope to find out from each.

Submit your findings

Once you've reviewed the evidence and are happy with your assessment, complete the email to DCI Mark Ellison below.

Your email should explain what evidence supports Fletcher's account, what evidence contradicts it, and what further enquiries you would recommend.

Only submit your email when you're satisfied with your findings and the reasons behind them. Once submitted, you'll be able to read my thoughts and compare your assessment with mine.
