The most shocking detail that came to light during the investigation was the claim that a male heart was discovered in Sanam's body, a revelation that intensified the mystery of her death.

A Birthday Night That Ended in Tragedy

Sanam Hasan, who was originally from Mumbai, had relocated to Pune to study fashion design. On October 3, 2012, she was celebrating her birthday with friends. After her friends urged her, her father allowed her to go to a late-night gathering at a luxury apartment in the city.

However, the celebration quickly turned into a tragedy. In the early hours of October 4, Sanam's family received a call saying she had suddenly become ill. Her parents hurried to Pune, but by the time they got there, their daughter had already died.

Post-Mortem Report Raises Startling Questions

Sanam's post-mortem was performed at Sassoon General Hospital in Pune, and the results raised alarming questions. The report reportedly indicated that the heart found in her body belonged to a male and had approximately 70 percent blockage.

This revelation left her family in shock and confusion. Sanam was known to be active and was said to be a football player with no known heart issues. The finding led to a troubling question: How could a young woman's body have a man's heart?

Suspicions of Sexual Assault and Foul Play

Investigators faced further issues when they discovered semen samples on Sanam's body along with marks from four injections, leading to concerns that she may have been sexually assaulted and killed.

DNA samples from 17 individuals who attended the party were gathered for analysis. However, none matched the evidence found on the body. Later, it was suggested that the heart might have been mistakenly swapped due to carelessness by hospital personnel. Still, the identity of the heart used as evidence has never been definitively confirmed.

CBI Probe Fails to Deliver Answers

In 2014, the case was handed over to the Central Bureau of Investigation (CBI). Two years later, in 2016, Sanam's body was exhumed for additional forensic analysis.

Despite the renewed investigation, the agency could not come to a clear conclusion. Reports indicate that investigators faced challenges due to the delay in evidence collection and alleged mishandling of forensic materials during the initial stages of the investigation.

Mystery That Remains Unsolved

Over a decade has gone by since Sanam Hasan's death, yet the case remains unsolved. It is still uncertain whether she died from a natural heart issue or was the victim of a well-planned crime.

If it was a murder, the culprit has never been found. The lingering questions about the case continue to trouble investigators and the victim's family, making the Sanam Hasan case one of the most baffling mysteries in India's criminal history.
