In a contentious case that has raised questions about forensic evidence and the criminal justice process, Nicole Chuminski, convicted in 2010 for an arson-related fire, continues to seek a new trial amid concerns over the reliability of the forensic analysis presented against her.
During the original trial, lab analyst Drugan testified that acetone was detected on wood and clothing samples related to the fire. While Drugan acknowledged the presence of acetone at trace levels, defense experts and independent chemists have since criticized the interpretation and presentation of this evidence. Two independent forensic chemists—Eric Hazelrigg, a former state lab analyst and university professor, and Glen Jackson, a forensic science professor and journal editor—reviewed the laboratory data without prior knowledge of the case and concluded that the acetone quantities were insignificant and did not necessarily indicate the use of an accelerant or deliberate setting of the fire.
Criticism also extends to the laboratory’s reporting practices. The ASTM E1618 standard, which guides ignitable liquid analysis, calls for caution in interpreting acetone presence, noting it is common in many commercial products and does not by itself prove intentional arson. However, Drugan’s report reportedly lacked these contextual clarifications, offering only that acetone was identified. Defense attorneys did not file pretrial motions to exclude this evidence, a step some argue might have prevented potentially misleading information from reaching the jury.
Further scrutiny has identified similar issues in other cases handled by the same analyst. One such case involved Frances Choy, who was convicted for a 2003 fire but later exonerated amid questions about forensic evidence. Another case involves Robert Therrien, convicted for a 2001 fire who remains imprisoned and maintains his innocence, describing the conviction as life-altering. Drugan, now director of the Boston Fire Department’s lab, declined to comment, while the former crime lab emphasized its longstanding national accreditation and commitment to scientific integrity without addressing specific cases.
The Suffolk County District Attorney’s office, responsible for prosecuting Chuminski, has not publicly responded due to ongoing legal proceedings related to her motion for a new trial.
Beyond forensic evidence, the case includes testimony from inmates who claimed Chuminski made incriminating statements while jailed before trial. These accounts, including admissions of argument and possible involvement in the fire, were challenged by defense attorneys citing the witnesses’ criminal backgrounds and potential incentives for cooperation. In addition, a witness testified that Chuminski admitted throwing a beer bottle through a window on the night of the fire, aligning with prosecution theories of a Molotov cocktail attack, though physical evidence to support this was lacking.
Chuminski, now in her late 30s, has spent more than a decade in prison and reports significant personal losses during this time. She has pursued education and vocational training while incarcerated and continues to advocate for her innocence, expressing hope that upcoming legal efforts will reveal the truth.
The case underscores broader concerns about forensic science’s role in the justice system, particularly regarding ambiguous evidence and the potential consequences of flawed or overstated findings. As calls for reform grow, observers stress the importance of ensuring fair trials for all defendants, especially in complex cases where evidence may not clearly indicate guilt or innocence.
