The Ransom Note
The Ransom Note
We’ve found 2 pens from the car of Al Burns - were they used to write the note?
You’ll need:
A glass of water
The ransom note
Evidence B & C
A pair of scissors
A piece of paper
What to do
What to do
Cut a small strip off the ransom note (it needs to contain some of the ink)
Place the end of the strip with writing on, into a glass of water and leave for 30 seconds
In the meantime, use the two pens (evidence B & C) & draw on their own strips of paper (Make sure you mark which is which...!)
Place the two new strips into the glass of water for 30 seconds
Once all 3 strips of paper are out of the glass compare the spread of the ink
Were either of the pens used to write the ransom note?
If these were found in Al Burn's Car, can you rule him out?
