Wednesday September 25th, 2019 // 11:45 am - 12:10 pm // Oasis 1-2

In 2014 Washoe County employee, Chris Long, was diagnosed with AML/MDS Leukemia. Chris underwent a stem cell/bone marrow transplant and volunteered to participate in a case study led by the Washoe County Sheriff’s Office Forensic Science Division. This case study is ongoing and monitors the fluctuation of DNA profiles from both the recipient and donor in various bodily fluids and tissues. Over the last four years Chris exhibited a full uptake of the donor’s DNA within his blood and dynamic fluidity of chimerism within other tissues. This study highlights the potential effects of chimeric fluidity in forensic DNA interpretation. Chris’s story is one of both medical success and the resilience of the human spirit. Recently celebrating four years cancer free, he strives to inspire others to work hard at enjoying what they have; by taking what life gives you and doing the best with it.
