Confessed Gilgo Beach serial killer Rex Heuermann has agreed to work with the FBI's Behavioral Analysis Unit.

The shocking case came to an end Wednesday when the 62-year-old Massapequa Park resident appeared in court and pleaded guilty to killing eight women.

Officials confirm that he will cooperate with the FBI as part of his plea deal.

The Behavioral Analysis Unit was established in 1972 to consult experts on "different, unusual or bizarre cases."

The department works in tandem with federal, state and local law enforcement partners.

They cover offenses such as terrorism, cybercrime, serial murder and other acts of violence.

Their work involves a variety of investigative strategies aiming to obtain further insight into the psychology of an offender.

According to the FBI, this includes analyzing "motivation, victim selection and sophistication levels."

FBI agents associated with the unit in the 70s assessed famous killers such as Ted Bundy.
