A New York judge in Riverhead has allowed DNA evidence to be presented in the case against Rex Heuermann, who is accused of being the Gilgo Beach serial killer. This decision was made on Wednesday and is significant as it involves DNA technology that has not previously been tested in a New York court.

Suffolk County prosecutors claim that the DNA links Heuermann to the murders of at least seven victims. They argue that DNA extracted from hair fragments found on the victims' bodies strongly implicates the Manhattan architect.

However, Heuermann's defense team has raised concerns about the reliability of the DNA analysis methods used. They argue that these techniques are unproven and should not be admitted as evidence.

Prosecutors countered that the technology used to analyze the DNA is based on accepted scientific methods. They successfully convinced the judge that the evidence should be allowed in court.

Experts suggest that this case could set a precedent, as it may be the first instance of such DNA techniques being accepted as evidence in New York. The outcome of this case could have implications for future legal proceedings involving similar DNA technology.
