In a disturbing twist to a complicated case, police say a woman who was under investigation for her son's death earlier this year was found dead along with her husband in their Frisco home.
Police were investigating Pallavi Dhawan for the death of her 10-year-old son in January. They say they found the 39-year-old dead in a swimming pool and her 43-year-old husband, Sumeet Dhawan, dead inside the home.
The medical examiner ruled his death a homicide, saying he died of blunt force injuries and high levels of Benadryl and Aspirin. Her death was ruled a suicide by Benadryl toxicity and drowning.
Police found a note, but have not released its contents. Police had charged Pallavi Dhawan with murder for the death of her 10-year-old son, Pallavi Dhawan, in January. They say his mother kept his body on ice for several days after his death and nodded when police asked if she'd killed her son. She and her husband denied 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 the boy's death, but also said the "unusual circumstances cannot be ignored."
The case has drawn criticism and raised questions about the role culture might have played in the police investigation. And Pallavi Dhawan's attorney said the investigation put the couple under "an incredible amount of pressure." Now, with the mother's death, police have said they'll close the investigation into her son's death.
