Overview

• Andrew Cobby's appeal for a retrial was dismissed by the Brisbane Court of Appeal, leaving his 2021 life sentence intact.
• Cobby argued that retested DNA evidence on the hammer, the alleged murder weapon, could have influenced the jury's verdict.
• The court found the fresh DNA evidence did not meet the legal standard to create a significant possibility of acquittal.
• Prosecutors emphasized that the hammer was only one of 13 pieces of evidence, including Cobby's blood-soaked clothing and his DNA under the victim's fingernails.
• The case highlighted broader issues with Queensland's forensic lab, but the court ruled the conviction remained supported by strong circumstantial evidence.
