TUPPER LAKE – Federal authorities are trying to determine whether a suspected serial killer was involved in the disappearance of a northern New Jersey woman, who they believe may be buried in the Tupper Lake area.

The FBI released a statement today that Keyes admitted that on April 9, 2009, he abducted a female victim from a state on the East Coast and transported that person over multiple state lines into New York. They go on to say Keyes murdered the victim and buried her in upstate New York near the Tupper Lake area.

Investigators believe the victim of the April 9, 2009 homicide may be Debra Feldman, who resided in Hackensack, N.J., at the time of her disappearance. To date, Ms. Feldman’s body has not been recovered.

Keyes is also suspected in the April 10, 2009 robbery of Community Bank in Tupper Lake. After his arrest in 2012, Keyes was charged with the murder of 17-year-old Samantha Koenig, an Anchorage barista who was kidnapped from the coffee stand where she worked. Her dismembered body was pulled from a lake north of Anchorage two months after she went missing. Keyes later confessed to the 2011 murders of a Vermont couple and indicated to authorities there were victims in a total of 10 states. Investigators believe Keyes did not know any of his victims prior to their abductions.

He was found dead of an apparent suicide in an Alaska jail cell last year.

Anyone with information about the disappearance of Feldman is asked to call 1-800-225-5324.
