Baby Boy Hernandez, an unborn Latino, was pronounced dead Sunday, Oct. 25, after his mother was found dead in the 7300 block of Neo Street in Downey, according to Los Angeles County coroner's records.
Police were called to the scene about 8 p.m. on Oct. 21 — an apartment the baby's mother, Reyna Hernandez, 26, shared with her boyfriend, Nicholas Christopher Quezada, 29, and their 1-year-old son, Jude Christopher Quezada, said Downey Police Lt. Mark McDaniel.
All of the family members were dead.
Reyna Hernandez was found in the bathroom with her toddler son. Both were in the bathtub, which was filled with water, McDaniel said.
Coroner’s records said Hernandez died from a forced drowning and Jude died from "asphyxiation — homicide.”
Baby Boy Hernandez was discovered during his mother's autopsy on Oct. 25, and pronounced dead then, said coroner’s Assistant Chief of Investigations Ed Winters.
Quezada’s body was found in the bedroom, and ruled a suicide by suffocation, according to coroner’s records.
Investigators believe Quezada killed his son and girlfriend before killing himself, McDaniel said. The family had lived in the apartment for more than a year and there was a history a domestic violence calls to the residence, he said.
Hernandez and Quezada had been living together for about four years, investigators said.
