Answer:
C. look for other evidence
Step-by-step explanation:
An antemortem dental record can be defined as a record of the information about the teeth of an individual (patient) performed before his or her death. These informations (dental records) can be used in investigation to determine the cause of death of an individual.
Basically, an antemortem record refers to the medical records or sensitive bodily informations obtained from a person before his or her demise.
In a car accident investigation, forensic investigators could not locate the antemortem dental record of the victim for comparative study. In order to increase the probability of locating the antemortem record, they should look for other evidence such as fingerprints, image of body tattoos, body tissue records etc.
