Christopher Daniel Lumbrera was a 5 ½-month-old Hispanic male who died on March 28, 1984. His death was originally ruled septicemia. At the time his family had already suffered multiple infant deaths that were attributed to natural causes.

After a later death in the family — 4-year-old Jose Antonio Lumbrera, found to have been smothered in 1990 in Garden City, Kansas — investigators reopened earlier cases. That review led to murder indictments in Texas and, following a no contest plea in 1991, a life sentence for Diana Lumbrera in Texas; she had previously received a life sentence in Kansas for Jose Antonio’s death. Authorities concluded Diana Lumbrera had suffocated several of her children, though Christopher’s initial cause of death had been recorded as septicemia.

Are there details from the 1984 hospital records, treatment notes, or family medical history that anyone can share to clarify Christopher’s final hours?
