Trial & Retribution (1997) : 10x9

The murder of a Police Commander and his wife puts Walker, Connor and the team under pressure to get a quick result. Jewelery has been stolen from the house, which would indicate a burglary gone wrong, but several relatives profit from their deaths and so they focus the investigation on the family. Connor is suspicious of the identical twin sons in particular and suspects that they may have worked together in order to get away with patricide.
