Because those personal bodily samples (among others) contain samples of the cell structure call DNA which is unique to every person on earth. The statistical odds of two people having the exact same DNA (EVEN identical twins) is so astronomical as to be insignificant.

no they find the DNA from the fingerprints and the look on the computer then the person who made the fingerprints his/her face will come on to the computer
Hair does not have unique characteristics like fingerprints do. While it can provide important information such as DNA analysis, hair evidence alone is not as definitive for identification purposes because multiple individuals can have similar hair characteristics.
No it does not. However, if there was blood, saliva, or sweat on the finger that made the print, it would theoretically be possible to collect the material and extract dna from it.
Blood slatters so they can tell how far it slpattered from and fingerprints and DNA of the person
Fingerprints. Blood group. DNA Fibre analysis.
No two individuals (except identical twins) have the same DNA fingerprints, as they are unique to each person. DNA fingerprints are also known as DNA profiles and are widely used in forensics and paternity testing because of their individuality.
