The team made a quick and efficient sweep of the building. 30 minutes later they reported that nothing suspicious had been found. The tenants had cooperated, and they had gained access to the two other appartments left on the list, without finding anything there. With nothing left for them to do, the ERU team started to pack up, about the same time as the CST team called it a night. Plenty of semen had been collected, and this time also a couple of pieces of hair, hopefully they did not belong to the victim.
