Who killed Hector's son?

Can you tell me, in detail, who was responsible for the tragic death of Hector's son? Have there been any suspects identified or arrests made in connection with this crime? What is the current status of the investigation, and are there any leads or clues that have emerged so far? This incident must be deeply distressing for Hector and his family, and I would like to know as much as possible about what happened and what steps are being taken to bring the perpetrator to justice.
