Overview

• New York State Justice Timothy Mazzei ruled that all seven murder counts against Rex Heuermann will proceed in one trial.
• The court rejected defense claims that differing timelines, methods and locations required multiple trials or risked overwhelming jurors.
• Mazzei also denied a renewed motion to exclude whole‑genome results from Astrea Forensics based on New York licensing, after previously allowing the advanced DNA analysis.
• Prosecutors say they are ready for trial and have certified full discovery, including a 723‑page inventory and a witness list, yet no trial date has been set.
• Heuermann has pleaded not guilty to killing seven women dating to 1993, with prosecutors asserting DNA links to six victims and the next court appearance set for January.
