Domestic Violence
The case involves a history of psychological and physical abuse within a dating relationship that ended in separation. Persistent harassment and stalking by the ex-partner escalated tensions. Family involvement, particularly the ex-partner's uncle, contributed to the fatal violence. The incident was triggered by an aggressive confrontation at the victims' home, culminating in a shooting.
The investigation is ongoing with suspects at large, including the shooter Sebastián “N”, the ex-partner Rumin “N”, two unidentified women, and an unknown driver. A neighbor's security camera captured part of the incident. Witness statements identify the shooter and suspect the driver. The shooter was under conditional release for armed robbery at the time.
The identities of the two women and the driver remain unknown. The exact roles of accomplices and the full sequence of events are still under investigation.
Alejandra ended a one-year abusive relationship with Rumin “N”. Despite the breakup, Rumin continued to harass her. On January 11, 2025, two unknown women arrived at the victims' home, aggressively confronting Alejandra. Andrea intervened to protect her sister. Sebastián “N”, Rumin's uncle, arrived armed and shot both sisters, killing them. Their mother was also shot but survived. The suspects fled the scene and remain at large.
High risk due to documented abuse, stalking, threats, and firearm access. The involvement of family members in the violence and the suspects being at large increase ongoing danger.
