Paramedics and police relive the moments they were called to Charlie Rowley's flat in Amesbury. First Dawn Sturgess is found unresponsive, and then several hours later Charlie falls ill too. The emergency services disagree about what has caused him to be so unwell. The Inquiry investigates whether Dawn could have survived if the initial treatment had been different.
