The Case Against Naresh Bhatt
Mamta, a pediatric nurse and mother, was last seen in late July 2024. Her co-workers contacted police after she failed to show up for work, and investigators eventually focused on the home she shared with Naresh. Court records and hearings later revealed evidence of what prosecutors allege was a violent struggle inside the house.
During a 2024 hearing, prosecutors said investigators found blood traces in the couple’s bedroom and a significant amount of blood in the bathroom. They also alleged that something appeared to have been dragged from the bedroom toward the bathroom. Investigators discovered cleaning supplies in the bedroom, including an empty bottle of carpet cleaner Naresh had purchased shortly after prosecutors believe Mamta was killed.
Prosecutors have pointed to other evidence surrounding Mamta’s disappearance, including Naresh’s purchases of knives and cleaning products and surveillance footage that they say shows him disposing of bags. He also allegedly searched ‘“How Long Does It Take to Get Married After Spouse Dies” in April 2024 from his work laptop, months before Mamta went missing.
Police later said DNA testing confirmed that blood found inside the house belonged to Mamta. A grand jury indicted Naresh on charges of murder and physically defiling a dead body in December 2024.
One piece of evidence in particular, a handheld power saw recovered from the couple’s home, is likely to receive myriad attention at trial.
An October 2024 Virginia Department of Forensic Science analysis found that blood on the saw matched a DNA profile created from Mamta’s hairbrush. Then, in May 2026, investigators submitted three human hairs and 13 hair fragments recovered from the same saw for additional forensic analysis.
Kelly Knight, a professor in George Mason University’s Forensic Science Program, tells A&E Crime + Investigation that investigators would first need to determine whether the hairs are suitable for DNA testing. If they are, analysts could develop DNA profiles and compare them with reference profiles, including the profile investigators derived from Mamta’s hairbrush.
Even if the hairs are identified as belonging to Mamta, Knight cautions against assuming that finding alone proves how they got onto the saw or who used it.
“They have already identified blood that belonged to Mamta on the saw, so identifying hairs that belong to Mamta on the saw could potentially provide additional support” for investigators’ theory about what happened, Knight says.
But forensic evidence alone cannot definitively establish how the blood or hair ended up there. Nor would finding Naresh’s DNA on the saw necessarily establish that he used it in a crime, Knight says. If the saw belonged to him and was kept at his home, his DNA might reasonably be expected to be present.
How Prosecutors Can Prove Mamta Kafle Bhatt Was Murdered
In a murder case, the prosecution must establish what lawyers call the corpus delicti, which is essentially proof that the crime actually occurred.
For murder in Virginia, that means establishing two things: First, that the victim died, but also that the death resulted from someone’s criminal act. Both can be proven through circumstantial evidence, according to Virginia Court of Appeals precedent. The Commonwealth also doesn’t have to recover a body or prove the exact physical manner of death if all of the evidence establishes the victim died as a result of a criminal act.
John Fishwick Jr., a Virginia trial attorney and former U.S. attorney for the Western District of Virginia, tells A&E Crime + Investigation that he expects Naresh’s attorneys to focus on the absence of Mamta’s remains and challenge the conclusions prosecutors draw from the physical evidence.
But Fishwick believes prosecutors can build their argument by combining what investigators found inside the home with evidence about Naresh’s alleged actions afterward.
“I think they’ll be able to prove beyond a reasonable doubt that she’s dead,” Fishwick says.
Still, jurors must also be convinced beyond a reasonable doubt that her death was a homicide, that Naresh caused it and that the evidence establishes the elements required for first-degree murder.
Fishwick expects the defense could try to neutralize some of the forensic evidence by pointing out that Mamta lived in the home where her DNA and blood were found.
“They’ll try to normalize the DNA evidence,” Fishwick says.
Knight says that illustrates the limitations jurors must keep in mind when evaluating a case built heavily on forensics. Forensic evidence is circumstantial, she says, meaning jurors must draw inferences from it rather than treating any one finding as a definitive account of what happened.
Jurors should consider alternative explanations for how particular evidence came to be where investigators found it, Knight says, while evaluating the totality of the evidence against the beyond-a-reasonable-doubt standard.
That is likely to become the central question of Naresh’s trial: whether blood, DNA, surveillance footage, purchases and other circumstantial evidence can tell jurors what happened to Mamta, despite investigators having never found her remains.
