On a summer day in the small community of Tres Piedras, New Mexico, the lives of a Hispanic woman and a man she was with were tragically cut short. On August 1, 2020, 47-year-old Nirvana Romero Sisneros and Nathan Faccio, 46, were discovered deceased inside their residence. The New Mexico State Police were called to the scene, and it soon became apparent that their deaths were not of natural causes.
The State Police Investigations Bureau took over the case, treating it as a double homicide.
In the days and weeks that followed, investigators worked to piece together the events that led to the deaths of Sisneros and Faccio. Numerous interviews were conducted, and multiple search warrants were executed as agents diligently pursued leads. Early in the investigation, law enforcement identified a person of interest, but an arrest was not immediately forthcoming. For over three years, the case remained a subject of ongoing investigation, leaving the community and the families of the victims awaiting answers and justice. The lack of a named suspect or a clear motive publicly released left a cloud of uncertainty hanging over the quiet, rural area.
A significant breakthrough in the case came in early 2024. An arrest warrant was issued for Warren Metzen in connection with the double homicide. The charges against Metzen were reportedly based on the account of a witness who claimed to have been with him at the time of the killings. When questioned by state police, Metzen alleged that the couple had drugged him and his family. He further claimed that his children, who had been staying with Sisneros and Faccio along with his ex-wife, were being abused. The investigation continues as the legal process moves forward.
