To be sufficiently valid to be used as evidence the latent prints must contain within them a certain number of identifiable "points." If the lifted prints do not contain enough points they are not useable as evidence in court but, nonetheless, may be used as an investigative tool, helpful in narrowing down the suspect pool.
Fingerprints can be lifted from paper using methods such as dusting with fingerprint powder, applying adhesive tape, or using sticky gel lifters. The paper surface is treated carefully to avoid smudging or damaging the fingerprints, and the lifted print can then be analyzed or used as evidence in investigations.
No, fingerprints cannot be permanently removed using chemicals.
Admissible as evidence
I don't think evidence is categorized... But..It would depend: if it is a hidden print, it will probably have to be discovered using some kind of chemicals such as luminol or simple things like powder, this meaning it will require forensics. So pretty much: 'Forensic evidence', But if it had nothing to do with discovering it using forensics, well, someone else will have to answer that for you.Added: It is known as PHYSICAL EVIDENCE.
The country where fingerprints were used to identify a woman who murdered her two sons is Germany. In 1902, the case of Betty Gow became the first documented instance of using fingerprints as evidence in a criminal investigation. Gow was convicted and executed for the crime.
Fingerprints alone are typically not enough evidence for conviction as they only prove that a person was present at a certain location. Other evidence, such as eyewitness testimony, DNA evidence, or surveillance footage, is usually needed to establish guilt beyond a reasonable doubt.
dna fingerprints and notes
Fingerprints were first used as evidence linking suspects to crime in the late 19th century. Sir Francis Galton, a British scientist, was one of the pioneers in the study of fingerprints for identification purposes. The first documented use of fingerprints in a criminal case was in Argentina in 1892.
So vague as to be unusable for evidence.
