Authorities are reviewing unsolved murder and missing persons cases to determine which cases, if any, may be linked to Keyes. Keyes confessed to at least one murder in New York State. Authorities have not determined the identity, age, or gender of the victim, or when and where the murder may have occurred, but regard the confession as credible. Keyes had ties to New York; he owned ten acres and a run down cabin in the town of Constable. Keyes also confessed to committing bank robberies in New York and Texas. The FBI later confirmed that Keyes robbed the Community Bank branch in Tupper Lake, New York, in April 2009. He also told authorities that he burglarized a Texas home and set it on fire. Keyes claimed to have killed a woman in April 2009 in New Jersey and buried her near Tupper Lake in upstate New York. Keyes also admitted to killing Bill and Lorraine Currier of Essex, Vermont. Keyes broke into the Curriers' home on the night of June 8 and tied them up before driving them to an abandoned farmhouse, where he shot Bill before sexually assaulting and strangling Lorraine. Their bodies have never been found. Two years prior to the Curriers' deaths, Keyes hid a "murder kit", which he later used to kill them, near their home. After the murders, he moved most of the contents to a new hiding place in Parishville, New York, where they remained until after his arrest. Keyes' last known victim was 18-year-old Samantha Koenig, a coffee booth employee in Anchorage, Alaska. Keyes kidnapped her from her workplace on February 1, 2012, took her debit card and other property, sexually assaulted her, then killed her the following day. He left her body in a shed and went to New Orleans where he departed on a pre-booked two-week cruise with his family in the Gulf of Mexico. When he returned to Alaska, he removed her body from the shed, applied makeup to the corpse’s face, sewed her eyes open with fishing line and snapped a picture of a four-day-old issue of the "Anchorage Daily News" alongside her body, posed to appear that she was still alive. After demanding $30,000 in ransom, Keyes dismembered Koenig's body and disposed of it in Matanuska Lake, north of Anchorage. An FBI report said Keyes burglarized 20 to 30 homes across the United States and robbed several banks between 2001 and 2012.
