State v. Crumpton: How the Washington State Supreme Court Improved Access to Justice in Post-conviction Dna Testing
Publication year | 2021 |
INTRODUCTION
Imagine you are incarcerated, spending day after day in prison for a crime you did not commit. With each appeal, hope and fear fill your mind. Ronald Cotton felt this way when he learned, after spending eleven years in prison for a rape he did not commit, that a court granted his motion for post-conviction DNA testing.(fn1) Ronald describes the period between the motion and the DNA results as a waiting game, a time filled with nightmares:
On the other hand, imagine you were the victim of a horrendous crime; you are trying to heal, and build a life outside of the pain inflicted upon you. As each court date approaches, you anticipate closure, only to find out there will be more court dates in your future. Jennifer Thompson-Cannino, the victim in Ronald Cotton's case, felt this way upon learning a court granted the man convicted of raping her post-conviction DNA testing.(fn3) Police asked Jennifer to give a sample of her blood for the laboratory to determine what DNA belonged to her and what belonged to her attacker.(fn4) Jennifer described how this felt:
These two perspectives illustrate the high stakes of post-conviction review and the very real impact it can have on people's lives. Although there are many different post-conviction review procedures and remedies, this Note focuses on post-conviction DNA testing. In particular, this Note analyzes the right to post-conviction DNA testing in Washington State under RCW 10.73.170, as the Washington State Supreme Court recently interpreted it in

I. UNDERSTANDING POST-CONVICTION DNA SCIENTIFICALLY AND LEGALLY
To understand the Washington State Supreme Court's holding in
Deoxyribonucleic acid (DNA) is a blueprint of an individual's genetic characteristics.(fn14) DNA can be anywhere.(fn15) The most commonly known sources of DNA evidence are blood, semen, hair, skin, and saliva; however, DNA can also be found on cigarette butts, bottles, clothing, or even a phone.(fn16) A "DNA match" occurs when a reference sample is compared with evidence and the DNA profiles are the same.(fn17) To make this comparison, first, a technician produces a DNA profile from a sample taken from the suspect-perhaps voluntarily or by court order.(fn18) Second, a technician produces a DNA profile from the biological evidence connected to the crime.(fn19) Finally, the technician compares the two samples' genotypes, and if there is a match, the technician determines the probability that a random person could have created the match.(fn20) This process produces an objective probability that the suspect was the source of the biological evidence from the crime "to an extremely high degree of confidence."(fn21)
It is tempting to assume that a DNA match between a piece of evidence and a suspect is determinative of that suspect's guilt.(fn22) Both prosecutors and defense attorneys assign DNA evidence such "mythic infallibility" as a forensic technique.(fn23) This myth has led to the idea that "DNA testing serves as a 'truth machine' that can definitively determine guilt or innocence beyond doubt."(fn24) But as the United States Supreme Court has recognized, "DNA testing alone does not always resolve a case;" where there is an explanation for the DNA result and enough incriminating evidence, DNA science alone will not prove innocence.(fn25) The utility of DNA evidence is far more complicated. As articulated by the National Institute of Justice:
Further, DNA tests do not always conclusively identify a particular person.(fn27) There may be inconclusive or uninterpretable results due to complications such as multiple contributors, contamination, or degradation of samples.(fn28) Complexities in DNA matching may increase more as scientific knowledge advances-for example, the increasing awareness of people with chimeric DNA.(fn29) Given the complexities of DNA evidence, the dilemma has become "how to harness DNA's power to prove innocence without unnecessarily overthrowing the established system of criminal justice."(fn30)
DNA testing in criminal trials in the United States began in the mid-1980s.(fn31) Usually, a petitioner obtains post-conviction testing through application under the law of the state of the conviction.(fn32) By the end of 2013, all fifty states had laws providing an avenue for post-conviction DNA testing,(fn33) but these statutes vary widely from state to state.(fn34) According to the National...
