Forensics, just like all aspects of science, are ever changing and improving.
There are new techniques out there for lifting fingerprints…even off of bullet casings.

Various cases of assorted common calibers.
British scientists have developed a new crime-fighting technique that allows police to lift fingerprints from bullets even if a criminal has wiped down a shell casing.Authorities in Britain and the United States used the method to re-open three cold cases, including a U.S. double murder that police are now optimistic of solving, said John Bond, the physicist who developed the technique.
The conventional method of taking fingerprints has been around for more than 100 years and involves creating a chemical reaction with the sweat left behind on an object to produce an image police can use.
But if a criminal wipes away the sweat, there is little left to react with the chemical and regular methods are useless, Bond said in a telephone interview.
The new technique allows police to outwit a criminal and produce a fingerprint even if there is no sweat impression to work with.
