The young woman, who was enrolled at a private nursing college near Khammam, had returned to her native village of Vengannapalem two days before her death.
Her mother found her lying beside the bathroom on the premises of their house on Tuesday evening after returning from farm work.
Villagers, shocked by the circumstances, immediately voiced suspicions of foul play and called for a thorough inquiry.
The Bhadradri Kothagudem police registered a case and dispatched a clues team to the scene to gather forensic evidence and determine the exact cause of death.
Authorities have not released any details about the findings of the preliminary investigation, and the family remains in mourning while awaiting further information.
