Question

bones make good evidence, but they do not contain information such as

evidenee of a surgery to remove a tumor on the brain

information relating to the age at death

possible evidence of severe fracture to the skull suffered in an auto accident

the dna of the perpetrator

Explanation:

Bones can show signs of fractures (like a severe skull fracture from an auto - accident) and can be used to estimate age at death (through methods like bone ossification and wear). However, bones do not contain the DNA of the perpetrator. DNA of the perpetrator would be found in biological samples like blood, saliva, or tissue of the perpetrator, not in the bones of the victim (unless the perpetrator's bones are involved, but that is not indicated here). Surgery to remove a brain tumor may leave some signs on the skull (such as a cranial opening for the surgery), but the key non - bone - related information is the perpetrator's DNA.

Answer:

the DNA of the perpetrator
