Final answer:
Forensic investigators arriving at a crime scene with no signs of lividity on the victim's body may indicate a relatively recent time of death.
Explanation:
Forensic investigators arriving at a crime scene finding a victim without lividity could suggest that the death occurred relatively recently, as lividity (pooling of blood in lower parts of the body) typically appears within 2-4 hours of death and becomes fixed after about 8-12 hours. Absence of lividity may indicate the victim hasn't been deceased long enough for this process to occur.
