These Jumbo sack where introduce back in the 90’s after Tetra visited a forensic laboratory, where there was over 15 large woodern doors stacked up against a wall, badly wrapped in polythene and lots and lots of brown tape. The incident that required such collection of so many large items, was due to a murder taking place in a high rise building.
The perpirator was covered in blood and when fleeing the crime scene had to push open every door, leaving fingerprints, fibre and blood evidence on every door.
