A young woman was murdered in Ipswich a month before Christmas. Karen Hales was at home with her 18-month-old baby when something or someone disturbed her.
Two boys walking near her home saw smoke, and locals saw a man running quickly across the road. Maybe you recognise him?
In Kent a family were held hostage throughout the night after robbers forced their way in at gunpoint. The two men, one posing as a postman, guarded them for 12 hours before taking the father, a jeweller, to his shop. He was forced to hand over the contents of the safe. As one of the robbers escaped he was seen by a local man. Can you help catch them?
