BANGOR, Maine — Nichole Cable died of “asphyxia due to compression of the neck,” according to the state medical examiner’s office.

Dr. Margaret Greenwald released her findings about the death of the 15-year-old girl from Glenburn and Alton on Thursday after consulting with the Maine State Police crime lab, which has been reviewing evidence in the case, according to a press release issued by state police.

The man accused of killing Cable is scheduled to be arraigned at 11 a.m. Wednesday at the Penobscot Judicial Center.

Kyle Dube, 20 , of Orono is expected to plead not guilty to one count each of kidnapping and murder. He is accused of luring Cable out of her mother’s home by using someone else’s identity on Facebook, then killing her in an abduction gone wrong.

Dube was indicted May 29 by the Penobscot County grand jury.

Superior Court Justice William Anderson has been assigned to Dube’s case but will be unavailable Wednesday. Justice Ann Murray will handle Dube’s arraignment and Anderson will deal with all other matters in the case.

Dube was charged on May 21 in connection with the death of Cable on Mother’s Day, the day she disappeared. Her body was found late May 20 in a wooded area of Old Town after Dube’s girlfriend and brother told police where Dube said he had left the girl’s body.

He 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.

Text messages between Cable and Dube show the two were together the night before she disappeared. Cable told her boyfriend the next morning, May 12, that she was upset the night before because Dube groped her and attempted to kiss her and then bit her, according to a search warrant affidavit filed by Maine State Police Detective Christopher Tupper released June 6.

“[Dube] wouldn’t stop and he ended up leaving a [bite] mark on me. So as soon as he got off me I had him bring me home,” she sent by text message at 8:48 a.m.

When police questioned Dube about the bite mark, “Dube stated while kissing Nichole she bit him and he bit her back,” Tupper’s affidavit states.

Dube created a fake Facebook page using the name Bryan Butterfield of Bangor to communicate with Cable and lure her out of her home, according to court documents.

“According to Nichole’s text messages and Facebook messages she was planning on meeting Bryan Butterfield at the end of her road to hang out for a few minutes, smoke marijuana, and get a free bag of marijuana,” Tupper’s affidavit states.

Police linked Dube, a 2011 Orono High School graduate, to the fake Facebook page because he updated the page using his cellphone, according to the Tupper affidavit.

The same cellphone was used to communicate with the 90-pound Glenburn teenager around the time she left her house, which her mother told investigators was about 9 p.m., the day she died. Cable was texting Dube about meeting Butterfield.

Investigators found a knit hat with an eye hole cut into it at the end of the dirt road in Glenburn near where Cable was staying and DNA found on the hat matched Dube, according to the Pickering affidavit. A sock found at the scene had DNA that matched both Dube and Cable.

One of her sneakers was found near the hat and the second one was found across the street, indicating to police that the girl attempted to run, the Tupper affidavit states.

Cable’s pink hoodie, torn up the front and dirty on the back with one sleeve turned inside out, was found several miles down the road, next to some black rope, according to the Tupper affidavit.

Dube was in Penobscot County Jail at the time of his arrest for murder. He reported to jail on May 17 to serve a 90-day sentence for charges stemming from a high-speed motorcycle chase last year that ended when he crashed into a police cruiser.

If convicted of the charges he faces in Cable’s death, Dube faces between 25 years and life in prison.
