For over two decades, criminal attorney Sarah Jenkins has built a reputation not by representing the wealthy or famous, but by challenging the very science used to convict thousands. Her latest victory, the exoneration of Robert Gaines after 22 years in prison, has once again thrown a national spotlight on the fallibility of bite-mark analysis, a forensic method she calls "unreliable pseudoscience."
Gaines was convicted in 2003 largely on the testimony of a forensic odontologist who claimed bite marks on the victim matched Gaines's dental impressions. Jenkins and her team at the Innocence Project revisited the case, bringing in a new wave of experts who testified that the methodology is subjective and has an alarmingly high error rate. DNA evidence collected from the scene finally excluded Gaines, leading to his release last week.
"We place our faith in science, but we must ensure that what is presented in a courtroom is genuine, validated science, not just an authoritative opinion," Jenkins said in an interview. "For every person like Robert Gaines we exonerate, we have to ask: how many more are in prison because of flawed techniques we once considered infallible?"
Jenkins’s work extends beyond individual cases. She is actively lobbying for federal and state-level reviews of convictions that relied heavily on now-discredited or questioned forensic methods, including hair microscopy and comparative bullet-lead analysis. Her advocacy has made her a controversial figure among some prosecutors, who argue she is attempting to undermine established justice systems. However, to the reform community, she is a crucial voice for scientific integrity in the pursuit of justice.
