Possessed: Part 1 Crown Court : Season 4 Episode 39

In an unusual case, the Crown Court has to decide whether Megwyn Spiteri is fit to stand trial on the charge of murdering her five-year-old twins David and Maria. The defence accepts that the children died after Mrs. Spiteri gave them an overdose of dexedrine. However, it asserts that she was unable to cope with them - they were difficult and disturbed - and killed them while suffering from psychotic delusions that they were possessed by demons. Mrs. Spiteri says she believes the children are still alive and that she "saved them", and the defence argues that this proves she is unfit for trial. However, the prosecution - while accepting her difficult personal circumstances - says that she knew what she was doing at the time of their deaths and now, and has invented the delusions to avoid trial.
