When Wang Song made a discovery, the Crime Scene Investigation team in Tianzhou City immediately began the facial recognition work.
With the advancement of criminal investigation technology, facial recognition is playing an increasingly important role in solving cases.
In many cases, when other technologies hit a dead end, facial recognition often provides investigators with new directions.
However, like fingerprints, facial recognition requires a massive database for support.
And this is often a significant shortfall.
"We can't pin all our hopes on facial recognition."
Every case handled by Li Donglin has been a major one.
His experience is exceedingly rich, especially with the three suspects in this family massacre case, who are extremely cautious and have a strong sense of anti-investigation.
Therefore, trying to identify them through facial recognition, let alone capture them, is indeed very difficult.
