BANGOR, Maine — A 15-year-old girl’s death was a kidnapping gone wrong, according to the affidavit released late Wednesday after the Penobscot County grand jury indicted Kyle Dube, 20, of Orono on charges of murder and kidnapping.

Kyle Dube was charged on May 21 in connection with the death of Nichole Cable of Alton and Glenburn on Mother’s Day, the day she disappeared. Her body was found late May 20 in a wooded area of Old Town.

Dube intended to “kidnap Nichole and hide her; that he would later find her and be the hero,” the affidavit, written by Maine State Police Detective Thomas D. Pickering, said.

Dube’s brother Dustin Dube told police that Kyle Dube said he had Cable “meet him down the road [from her house]; that he waited in the woods wearing a ski mask; that he had duct tape; that he jumped out of the bushes and took Nichole; that he duct taped her; that he put Nichole in his father’s pickup truck; that when he removed Nichole from the truck she was dead; that he dumped Nichole’s body in the woods near the Dysart’s gas station in Old Town; that Nichole is in the woods covered in sticks.”

Kyle Dube’s girlfriend told police that he had told her a similar story and also said he had thrown Cable’s clothes out the window of the truck on his way back, the affidavit said.

When interviewed by an investigator on May 15, Kyle Dube said he had a relationship with Cable but was working in Bangor the night of May 12. He said that he had texted her earlier in the day, the affidavit said.

Kyle Dube created a fake Facebook page using the name Bryan Butterfield of Bangor to communicate with Cable, according to the affidavit. Investigators learned of the page from the real Butterfield on May 14 after one of Cable’s friends said the 15-year-old had sent her a text on May 12 stating she was meeting “Butterfield.”

Butterfield told investigators that he suspected Dube had created “this fraudulent Facebook account; that he knew that Kyle wanted to have sex with Nichole, but that she has refused his advances,” the affidavit said.

The document does not explain how Butterfield knew Dube or Cable.

In reviewing Cable’s Facebook account, investigators learned that she had frequent contact online with the fake Butterfield.

“The person posing as Butterfield repeatedly requested to meet with Cable in person,” the affidavit said. “On May 12, Cable agreed to meet with this subject for the purposes of obtaining some marijuana.”

According to their Facebook communication, Cable was to have met the fake Butterfield at the end of her driveway, located in a remote section of Glenburn on a dirt road.

Investigators traced the IP address for the fake Butterfield’s Facebook page to the Orono home where Dube lived with his parents, the affidavit said.

Investigators also were able to link Cable to Dube through DNA evidence, according to the affidavit. A blue hat with a hole cut in it, a sock and black sneaker were found on May 14 in a wooded area near Cable’s mother’s home in Glenburn. Dube’s DNA, obtained May 15, was found on the blue hat and on the sock. Cable’s DNA also was found on the sock. Whose DNA was found on the shoe is not stated in the affidavit.

Cable was reported missing to the Penobscot County Sheriff’s Office by her mother, Kristine Wiley, at 8:27 a.m. May 13, the affidavit said.

Dube is being held without bail at the Penobscot County Jail. An arraignment date has not been set.

Deputy Attorney William Stokes said shortly before Dube was indicted that the medical examiner had ruled Cable’s death a homicide. He said exactly how the girl died could not be determined until tests are completed by the Maine State Police Crime Lab.

Cable’s funeral service drew about 300 people Monday at Bangor Baptist Church. Her private burial was held Tuesday at a cemetery in Alton.

If convicted of murder, Dube faces between 25 years and life in prison.
