Who planted the bomb on the train? How was the will forged? Why did the plastics factory explosion occur? Who ran over the child and drove off? What banned stimulant was the athlete taking? Which internet sites had the suspect accessed? What was contaminating the water supply? Is the new drug truly pure? Which company polluted the river and killed all the fish?
The challenge for these chemists is to collect, analyse and characterise the smallest traces of DNA, fibres, explosive residue, pollutants, drugs, etc. and then to impartially assess the significance of the samples to the issue being investigated.
