New efficient and fast methods have given DNA technology a boost.
And Marie Allen believes that the new technology makes it possible to look through previously unsolved crimes.
- Especially the "cold case" investigations where there is DNA saved and where you previously had too little DNA to get a DNA profile, she says.
One of the major areas of development in DNA since it began to be used routinely in the 90s is the amount needed.
From a blood stain as large as a single crown, you can now get DNA from a stain that is barely visible.
But will it ever be like we see in crime series on TV or action movies in cinemas?
Maybe not, but we may be approaching.
- We can make a DNA-based phantom image, so there we approach what we previously thought was science fiction, she says.
