Judge Kelli Johnson is conducting an in-camera review of 25 emails between prosecutors and a blood spatter expert to investigate a potential Brady violation. The review comes as defense attorneys challenge A.J. Armstrong's 2023 conviction for the 2016 murders of his parents, Antonio and Dawn Armstrong.
Why it matters
The defense alleges that prosecutors failed to disclose critical information regarding expert Celestina Rossi, who faced accusations of planting evidence in another case. This hearing will determine if the nondisclosure impacted the trial's fairness and the reliability of Rossi's testimony.
A.J. Armstrong is currently serving a 40-year prison sentence following his 2023 conviction. The court is now evaluating whether procedural errors occurred during the trial.
