<h1>Authorities refer probe to CBI and order third AIIMS autopsy after family rejects suicide finding amid protests</h1> State authorities will hand the investigation of a 19-year-old teacher's death to the CBI and have sent the body for a third autopsy at AIIMS after two earlier post-mortems; this follows sustained village protests and public outrage. Police reported evidence of insecticide in viscera, a purported suicide note and purchase records, and earlier post-mortems reportedly ruled out sexual assault, but the family rejects the suicide finding and refused cremation, prompting protests that included roadblocks and suspension of mobile internet and bulk messaging in the districts. Opposition figures and a women's commission have criticised the state response and demanded an impartial probe.
