Human hairs found on a handheld power saw from a Manassas home are adding another unsettling layer to the disappearance of Mamta Kafle Bhatt, a mother and pediatric nurse who vanished in late July 2024 and whose remains have still not been located. Her husband, Naresh Bhatt, remains jailed on charges that include murder, concealing a dead body and physically defiling a dead body.
The Virginia Department of Forensic Science recently reported finding three human hairs, 13 hair fragments and what appeared to be fibers and debris on a reciprocating saw taken from the couple’s house, according to WTOP. State lab certificates highlight that saw, a handheld reciprocating tool investigators say was tested multiple times during the probe, as a central focus of forensic testing.
An earlier state forensics report filed on Oct. 29, 2024, stated that blood detected on parts of that same saw matched a DNA profile built from Bhatt’s hairbrush. Prosecutors cited that link when a grand jury later upgraded the charges against her husband, as reported by The Washington Post. Prosecutors have said that DNA connection was a key piece of their case.
Investigators have also pointed to video and transaction records that they say show Bhatt discarding bags and buying items consistent with efforts to remove or hide evidence. Court filings and surveillance footage described by Fox5 DC allegedly show him dropping multiple plastic bags into dumpsters after leaving his child with a babysitter, purchasing a 40-pack of heavy black trash bags and a set of knives, and later moving bags from his Tesla into a trash compactor. Prosecutors argue that the timing and content of those transactions strengthen the circumstantial case against him.
Legal Hurdles Ahead
Because Mamta Bhatt’s remains have not been found, the commonwealth will have to prove an unlawful death through forensic and circumstantial evidence rather than a recovered body. The FBI has outlined how no-body prosecutions are built by establishing the corpus delicti through a constellation of proof, including forensic traces, digital records and witness testimony, and has published guidance that investigators use in such cases, according to the FBI. Prosecutors in this case say the lab certificates, surveillance evidence and transactional trail together form that kind of constellation, and law enforcement officials have publicly said they believe the evidence points to homicide, according to reporting by the Associated Press.
What’s Next
Court calendars list a jury trial start date of Oct. 10, 2026, with months of pretrial motions and likely battles over expert testimony expected before then. The handling and admissibility of the lab certificates, surveillance video and chain-of-custody records are expected to be major issues as defense attorneys attempt to exclude or limit forensic testimony, according to reporting and court filings. Judges in no-body prosecutions typically work through lengthy pretrial schedules to resolve those disputes before a jury is seated.
For Mamta’s family and the neighbors who have organized searches and vigils, the new lab certificates represent another public development in the case, not an end to it. Supporters have filled courtrooms and held public gatherings while officials continue looking for remains and building the prosecution, as noted by The Washington Post. As the case moves toward trial, prosecutors say they will lean on the state lab work and the documented paper trail to try to convince a jury.
