“Hayward Man Arrested for Allegedly Killing His Wife in Domestic Violence Case”
A Hayward man has been arrested for allegedly killing his wife following an investigation into her suspicious death, authorities reported.
The incident occurred on September 23 in the 27000 block of Eucalyptus Court, near Tennyson High School. Police responded to a 911 call from a family member at the residence, indicating that something had happened inside the home.
Upon arrival, officers found 47-year-old Tania Afanador unresponsive, and she was pronounced dead at the scene. They also discovered her husband, 47-year-old Alvaro Sierra, suffering from apparent self-inflicted lacerations.
Sierra was transported to a hospital for treatment and was arrested on Saturday while still recovering. He was discharged the following day and subsequently booked at Santa Rita Jail in Dublin on a murder charge.
Details surrounding Afanador’s death remain undisclosed. Authorities confirmed that the couple was legally married, lived together, and had no children.
