Lukis Anderson, a 26-year-old homeless man living in downtown San Jose, was arrested and charged with the murder of Raveesh Kumra after his DNA turned up on the 66-year-old Monte Sereno investor's fingernails — even though Anderson had never met him and was miles away, unconscious in a hospital bed, when Kumra was killed.
Kumra was murdered at his 7,000-square-foot Monte Sereno mansion during a home invasion, according to The Marshall Project, which places the attack around midnight on November 29, 2012; CBS San Francisco has reported the killing occurred the night of November 30. A group of burglars tied up and blindfolded Kumra and his companion Harinder, gagging them with novelty mustache-print duct tape before fleeing the scene. Harinder, still blindfolded, felt her way to a kitchen phone and called 911 after the men left. A coroner concluded that Kumra suffocated from the duct tape. Paramedics who responded were the ones who declared him dead at the scene.
A DNA Hit That Didn't Add Up
When police found Anderson's DNA on Kumra's fingernails, they believed it indicated the two men had struggled while Anderson tried to tie up his victim, per the Marshall Project's reporting. Anderson was arrested and charged with murder, a charge that could have carried a death sentence in California at the time. As the outlet IFLScience notes, a police officer reportedly told Anderson, “In all the years I've been doing this I've never seen a DNA hit being wrong.” Rattled, Anderson reportedly told his public defender, Kelley Kulick, “Maybe I did do it,” while also saying, “I drink a lot,” according to the Marshall Project's account.
But the timeline didn't fit. Anderson had collapsed in a local store after heavy drinking on the night of the burglary and was hospitalized with a blood alcohol level of .40 — five times the legal limit — at Santa Clara Valley Medical Center in San Jose, the same night Kumra was killed, per CBS San Francisco. He remained in the hospital overnight, giving him an alibi that placed him many miles from the crime scene. Kulick worked with a hired investigator to dig into Anderson's medical and mental health history, building the case that he could not have been at the mansion.
How the DNA Actually Got There
Investigators ultimately believed a pulse oximeter may have transferred DNA between patients' fingers, contaminating the crime-scene evidence, according to IFLScience's account of the case. CBS San Francisco reported that the same two paramedics who treated Anderson that night later responded to Kumra's home, and prosecutors said the transfer could have happened simply through contact between the paramedics' bodies, their clothing, and both men. The outlet described the case as likely the first documented instance in the country involving a paramedic transferring DNA in this way. Charges against Anderson were dropped after he had spent more than five months in jail.
The Real Culprits Behind Bars
While Anderson sat in jail, the actual path to the crime ran through a very different set of connections. DNA on the duct tape used at the scene was linked to Deangelo Austin, 22, while DNA on gloves left behind was linked to Javier Garcia, 21, whose attorney was Christopher Givens. Austin's older sister, Katrina Fritz, had worked as a sex worker and confessed that she had given her brother details of the house layout before the burglary — Kumra had reportedly visited her regularly over 12 years. Austin had links to a gang that regularly carried out burglaries, and police believed a friend of his, who had previously been in jail with Anderson, connected Austin with Anderson as a potential local burglary accomplice. That friend had reportedly traveled to San Jose while wearing an ankle monitor just days before the murder. Cell phone data confirmed the locations of Austin and Garcia on the night of the crime, and all three other defendants were ultimately convicted in connection with Kumra's killing. Givens suggested, per the Marshall Project, that Anderson might have pleaded to something or accepted a deal out of fear had the DNA transfer never come to light.
When Touch DNA Points the Wrong Way
The Anderson case is a stark illustration of a broader forensic problem. In one DNA-transfer experiment cited by the Marshall Project, a third of volunteers ended up with another participant's DNA on their palms despite never touching each other, and a separate study of 105 public objects found human DNA on 91 percent of them. An average person may shed more than 50 million skin cells a day, and labs today can identify someone from just a handful of cells — a sensitivity that cuts both ways when it comes to solving, or misdirecting, a case.
Touch DNA has been collectible from surfaces like door handles since researchers first demonstrated it was possible in 1997, as Scientific American has reported, and federal guidance from the National Institute of Justice confirms such evidence can be pulled from doorknobs, window latches, and steering wheels, not just bloodstains. In one study referenced by Scientific American, the person identified as the main contributor of DNA on a knife had never actually touched it in a fifth of the samples collected. Comparable mix-ups have surfaced elsewhere: in 2011, a man named Adam Scott was wrongly matched to a rape sample in Manchester despite living more than 200 miles away and never having visited the city, a mix-up later traced to a reused lab analysis plate, according to JSTOR Daily. In a separate case described by the same outlet, a man with Parkinson's disease was convicted of burglary on a partial DNA match before additional testing exonerated him.
Guidance tied to the National Institute of Standards and Technology suggests investigators should weigh the totality of the evidence in a case rather than leaning on an isolated DNA fragment that might not be relevant. The Anderson case shows what can happen when that caution gets skipped — a homeless man with a severe drinking problem, hospitalized and unconscious, nearly paid with his life for a murder his own body never witnessed.
