The forensic experts at BYL Nair Hospital here, who submitted a 26-page report to Khar police station last week, have expressed doubts that the samples received might have got mixed up and may not belong to Sheena Bora.
JJ Hospital had handed over the samples to Khar police last month, after which the evidence was forwarded to Nair Hospital. But the forensic team of the hospital, in its report submitted to police pointed out that the bone samples do not match with those that had been collected by the Pen police in May 2012.
"If there is a mix-up of samples, then it will surely dampen the efforts of forensic recreation of the crime," a police official said.
When asked, In-charge of Khar police, Dattatrey Bhargude, refused to provide any details of the report.

Interestingly, Mumbai police has already established a DNA match between Sheena Bora and Indrani Mukerjea with the help of the bones exhumed recently by the Khar police.
When Mumbai police launched probe in the case, Pen police claimed that they had sent a right humerus (long bone from shoulder to elbow), two teeth, a burnt skin patch and strands of hair to JJ Hospital for age, gender and cause of death analysis in 2012. The JJ Hospital subsequently handed over the 2012 samples to Khar police on August 28.
Indrani Mukerjea, her former husband Sanjeev Khanna and their driver Shyamvar Rai are in judicial custody over their alleged complicity in the murder.
Maharshtra government had last week referred the case to the CBI.
