Details about the trial against alleged Gilgo Beach serial killer Rex Heuermann could soon come into focus.

Today, both sides will go before Supreme Court Judge Timothy Mazzei to schedule any and all outstanding motions and hearings that must be addressed before trial.

Mazzei previously ruled on many of the big issues raised by Heuermann's defense team last year.

Last September, the judge rejected the defense's attempt to toss out the prosecution's key DNA evidence.

The evidence stemmed from rootless hairs found on or near the remains of six of Heuermann’s alleged victims. According to court documents, a total of nine hairs were recovered. Prosecutors argue that these samples link Heuermann, a Massapequa Park resident, to the crimes.

Heuermann's defense attorney argued that the DNA technology, known as whole genome sequencing, was not widely accepted and therefore should not have been permitted.

Mazzei also ruled that Heuermann will face one trial for all seven of his alleged victims. Heuermann's attorney, Michael Brown had petitioned to separate them by victim.

Heuermann is accused of killing seven women: Melissa Barthelemy, Megan Waterman, Amber Costello, Maureen Brainard-Barnes, Sandra Costilla, Jessica Taylor and Valerie Mack, between 1993 and 2011.

He has pleaded not guilty to all charges.
