The investigation into the murder of Samuel Luiz was the first in Spain to use the artificial intelligence.

The key to solving the case was artificial intelligence. “It’s the first case in which it is usedtransforming night into day helps us, also labeling the clothes of the aggressors and the murdered,” explains Agudo.
