Family members of Hector Lionel Alfaro, the man at the center of a shocking murder-suicide in Lakewood, California, have made a stunning request to authorities: conduct DNA testing on a deceased female relative—a granddaughter—who passed away prior to the tragedy. They claim to have uncovered suspicious details surrounding her death that may have triggered Alfaro’s “impulsive outburst,” leading to the fatal shootings of his wife, Roxana Rodriguez, and their 17-year-old daughter, Sienna Alfaro.

The incident unfolded in early January 2026 when deputies responded to a home on Lorelei Avenue around 8 a.m. They discovered Alfaro, 52, deceased from a self-inflicted gunshot wound in the den, alongside Roxana Rodriguez, 48, and Sienna, both killed by upper torso gunshot wounds in separate bedrooms. A 19-year-old daughter survived after Alfaro fired at her multiple times but missed, before he turned the weapon on himself. Two firearms were recovered at the scene, and law enforcement quickly ruled it a murder-suicide amid apparent domestic tensions.

In the aftermath, a candlelight vigil honored the victims, with community members describing Sienna as a “ray of sunshine” and avid soccer player. A GoFundMe campaign for the surviving siblings surpassed $70,000 to cover funerals, counseling, and support. The case appeared closed, with no initial indications of foul play beyond the perpetrator’s actions.

Now, however, Alfaro’s family is pushing back against the official narrative. They insist that unresolved questions about the death of a young female relative—referred to as a granddaughter—hold the key to understanding why their son and brother carried out the act. According to their claims, newly discovered inconsistencies or “suspicious points” around that earlier loss may have pushed Alfaro to a breaking point, framing the shootings not as random violence but as a tragic, explosive reaction to long-buried family pain.

Authorities have not yet commented publicly on whether they will pursue the DNA request, which could involve exhumation or re-examination of records if the relative’s death was previously ruled natural, accidental, or unresolved. DNA testing in such contexts typically aims to confirm or rule out biological links, paternity/maternity issues, or hidden connections that might alter perceptions of motive.

The development has stirred online discussions, with some questioning if deeper family secrets contributed to the domestic breakdown. Others express sympathy for all sides, noting the profound grief rippling through relatives on both ends. As the surviving daughter grapples with trauma and the community mourns, this unexpected call for genetic clarity could reopen wounds—or provide answers—in one of Southern California’s most heartbreaking recent cases.
