Ever Alexander Navarrete Sentenced to Life for Killing Signia Díaz

He can apelar todo lo que quiera, pero me voy a asegurar hasta mi último día en este mundo de que nunca salga de ahí, afirmó Óscar Díaz a N+ Univision regarding the life sentence handed down to Ever Alexander Navarrete for the murder of his mother, Signia Concepción Díaz.

Signia Concepción Díaz, a 48-year-old native of Honduras who also appeared in official records under her naturalized American name Karly Kimberly Navarrete, was shot at least 11 times and killed by her husband, Ever Alexander Navarrete, in the early hours of Oct. 1, 2023, univision.com reported. The couple had lived together for more than 30 years in Rosenberg, Texas, sharing three children.

Three years after the killing, the case remains tied up in appellate courts following a life sentence issued against Ever Alexander Navarrete in March 2026. Legal defense filings have pushed back scheduled court dates for oral arguments, with a current target set for Nov. 5, 2026, according to official court registers cited by univision.com. The ongoing appellate process could stretch across several additional months before reaching a final resolution.

Signia Leaves Husband to Move into Houston Residence

Signia spent years enduring emotional and physical abuse while waiting for the right moment to leave her husband, according to interviews given by her daughters Karly and Kimberly to N+ Univision. On the morning of Saturday, Sept. 30, 2023, she left the Rosenberg home she shared with Navarrete to move into a residence in northwest Houston, where she planned to live with her daughter Kimberly while finalizing her official divorce.

Residential security cameras captured Signia carrying a small potted plant out of her old garden to take to her new home. Days before receiving the keys to the property, her son Óscar had grown deeply concerned about the separation, warning his younger brother Jonathan that their father would become violent upon discovering the split. Óscar recalled a conversation where his mother told him that Navarrete was threatening her, prompting him to urge caution given Navarrete’s past actions.

Leigh Goodmark, a domestic violence expert from the University of Maryland, explained to N+ Univision that attempting to leave an abusive relationship sharply elevates danger levels as the abuser faces a perceived loss of control. On the day she received the keys, Signia brought Iván Díaz to the house to help with minor repairs, unaware that Navarrete had already initiated a tracking and assassination plan.

The Pursuit Across Borders And The Court Appeal

Following the October 2023 shooting, Ever Alexander Navarrete fled to his home country of El Salvador. Signia’s children tracked his movements themselves, utilizing emails and direct pressure on international authorities to secure an Interpol Red Notice that led to his arrest and return to the United States for trial, according to Óscar Díaz.

Although a court delivered a life sentence in March 2026, Navarrete’s defense team filed an appeal that has repeatedly shifted on court dockets. Óscar Díaz stated to N+ Univision that he intends to apply the same level of personal pressure to ensure Navarrete remains behind bars permanently despite the ongoing legal challenges.

Domestic violence homicides frequently involve heightened risk during periods of separation, echoing patterns identified in spousal abuse cases across the United States.
