Unlawful questioning, torture and unreliable evidence are the key reasons the two Myanmar men accused of the murder of two Britons on Koh Tao should be acquitted, the defence lawyer team told a court Monday.The team, working under the Lawyers Council of Thailand, submitted a 56-page closing statement to the Koh Samui Provincial Court. The team is trying to convince the court to acquit two Myanmar suspects -- Zaw Lin and Win Zaw Htun. They are accused of raping and killing British tourist Hannah Witheridge, 23, and murdering David Miller24, on Koh Tao on Sept 15 last year. The court will hand down its ruling on the case on Dec 24. In their statement, the defence says the questioning and charging of the accused prior to their prosecution was unlawful. The accused were questioned as "witnesses" but this turned into confessions to murder and rape.
