Joanna Garza was a three-month-old Hispanic female who died on November 30, 1976, in Friona, Texas. Her death certificate lists the cause as strangulation due to asphyxiation due to convulsive disorder, and no autopsy was performed at the time because the death was not considered suspicious.

Joanna was one of several children of Diana Lumbrera who died over a 14-year span under questionable circumstances. Medical personnel originally recorded natural causes for multiple deaths, but the pattern drew scrutiny after the four-year-old José Antonio Lumbrera died in Garden City, Kansas, of asphyxia due to smothering. Diana Lumbrera was later convicted in connection with José Antonio’s death and received a life sentence; prosecutors subsequently pursued additional murder indictments in three Texas counties alleging she systematically killed her children and concealed those acts by citing medical conditions.

Joanna’s case is part of that broader investigation and indictment sequence. Does anyone have additional details about Joanna’s death or the family’s medical history that might shed light on how these deaths were initially classified as natural?
