Initial details about the Frisco boy’s death were disturbing: his mother kept his body on ice in a bathtub for several days, and police say 38-year-old Pallavi Dhawan nodded when asked if she killed her son. She and her husband deny that.
Her husband said Arnav suffered from health problems, and that his wife tried to follow Hindu custom by keeping the body intact until he returned to town from a business trip.
The medical examiner's report ruled "natural disease” the most likely cause of death, but also said that "the unusual circumstances cannot be ignored, thus raising the possibility of an unnatural cause of death."
The case continues to draw criticism and raise questions about the role that cultural issues may be playing in the investigation.
