touch DNA to help build their case against James Biela for the murder of Brianna Denison. Touch DNA was collected from the doorknob of the residence where Brianna was staying when she was abducted. A DNA sample obtained from panties found near the body was later matched to the touch DNA and to Biela himself. December 2012 a homeless man named Lukis Anderson was charged with the murder of Raveesh Kumra, a Silicon Valley multimillionaire, based on DNA evidence. Anderson was drunk and nearly comatose, hospitalized, under constant medical supervision, the night of the murder. Anderson's DNA was accidentally transferred to the crime scene by paramedics who had arrived at Kumra's residence. The paramedics had treated Anderson earlier the same day—accidentally transferring Anderson's DNA to the crime scene hours later. The case was presented to the annual American Academy of Forensic Sciences meeting in Las Vegas, as a definitive example of a DNA transfer implicating an innocent person. In December 2015, police officer Daniel Holtzclaw was convicted of 18 felony counts, charges stemming from allegations of sexual assault, based on Touch DNA found on one of the alleged victims.
