Review the witness statements mentioning Arthur's whereabouts after his argument with Albert. Who saw him, and when?

Consider the timing of the argument and how long it might have lasted. How does this align with the estimated time of the incident?

Are there any discrepancies between Arthur's account and those of other guests? Do their stories corroborate his version of events?

Evaluate how these details impact the credibility of Arthur's alibi. Does the evidence support or undermine his claims?

Arthur admits he had a heated argument with Albert around 7:00 pm, lasting "what seemed like an hour," suggesting a possible motive. The Lovells' witness statement confirms they saw Arthur and his wife rejoin the party after 8:00 pm, socialising with guests up to the estimated time of the incident around 9:00 pm. No discrepancies exist between Arthur's account and other witnesses, strengthening his alibi. The suspicious red splatter on the burnt termination document is explained in the police report as a known printer/scanner issue, reducing its significance. Considering these factors, Arthur's alibi appears solid, making his involvement less likely.
