A hand-drawn timeline. There is a line along the middle which goes from 7pm on the left side to 8pm on the right side with the time at ten minute intervals marked out at regular points along the line (7.10pm, 7.20pm etc). Above the line the suspect’s account is shown, with what the suspect claimed to be doing between certain times marked against the time points. Below the line information from witness accounts and other evidence is marked at relevant time points, allowing the discrepancies between different sources of information to be seen.
