Despite the evidence of the Ramsey family’s involvement in the murder, some argue that DNA testing pointing to an unidentified male proves the Ramsey family’s innocence, and provides evidence of a break in. According to County District Attorney Mary Lacy, “touch DNA” technology, had convinced her that neither he (John), Patsy nor Burke was involved in the killing. Rather, test results pointed to an “unknown male.” (Finn). 

However, relying on DNA testing is unreliable. The DNA evidence could be a composite of many individuals because, so many were in and out of the crime scene and in contact with JonBennet’s crime scene and body. Troy Eid, a former U.S. Attorney for Colorado states, “”It’s a rather obvious point, but I mean, if you’re looking for someone that doesn’t exist, because actually it’s several people, it’s a problem,” (Brennan, Vaughan). Additionally, William C. Thompson, a professor in the Department of Criminology, Law and Society at the University of California-Irvine and an authority on DNA evidence stated, “It’s certainly possible that an intruder was responsible for the murder, but I don’t think that the DNA evidence proves it” (Brennan, Vaughan). The DNA leads cannot be relied on because so many people were in and out of the crime scene, and JonBenet’s body was moved multiple times. The DNA tested in the case could belong to a mixture of people because of the contaminated crime scene.
