Nichole Cable Update: Friend says man charged in missing Maine girl's death knew her; suspect appears in court

(CBS/AP) BANGOR, Maine - Nichole Cable, a 15-year-old Maine girl found dead in woods north of Bangor, knew the man charged with killing her, her best friend said, contrary to early reports that before her disappearance she'd headed outside her Glenburn home to see someone she recently met on Facebook.

Kyle Dube, 20, of Orono, had been friends with the victim for a couple of months, and they'd made plans to see each other the weekend that she disappeared, said Tyler-Ann Harris, 16, who described herself as Nichole's best friend.

Dube appeared in court Wednesday, a day after he was charged with murder when a body believed to be Nichole's was found in Old Town. He didn't show any emotion. A bail hearing will be held later.

Police so far have declined to reveal the circumstances of her death, describe her relationship with Dube or discuss the evidence they have against him. Nor is it clear whether a Facebook relationship had anything to do with her disappearance and homicide.

Justice William Anderson on Wednesday ordered a state police affidavit impounded at the request of Dube's lawyer. He said he will issue a decision by the end of the day on whether the affidavit can later be released.

Dube was already in jail serving a sentence for fleeing police on a motorcycle at more than 100 mph when he was charged Tuesday, according to state police. Steve McCausland, a state police spokesman, said investigators believe Dube is "solely responsible for her death."

Harris said Tuesday that Dube and Nichole planned to see each other the weekend she vanished, in April, before he was required to report to jail. Harris, who attended Old Town High School with Nichole, said she was surprised that Dube was charged in her death because she thought the two got along.

She described Nichole as someone who enjoyed life.

"She was really happy even though she went through a lot of hard stuff in her life. She always knew how to see the bright side of things," Harris said, dabbing her eyes with a tissue.

Dube's parents live in a tidy brick and white-sided house in Orono. A young man who answered the door Tuesday said the family didn't want to talk and closed the door.

Until quitting last week, Dube had worked since last June for The Getchell Agency, a Bangor organization  that cares for people with disabilities. The agency's CEO, Rena Getchell, said in an email to The Associated Press that his background check and employee reviews were satisfactory.

"He gave us no reason to believe that he might be capable of this crime," she said. "This is devastating news to us as we truly are a family."

The body believed to be Nichole's was found at about 9:30 p.m. Monday by a warden who was searching the woods with a dog, officials said. The medical examiner took possession of the body to make a positive identification and issue a ruling on how she died.

Nichole's mother, Kristine Wiley, said after she disappeared that Nichole had said she was going out to meet someone she knew from Facebook. But Wiley said she didn't know the identity of the person.

Dozens of law enforcement officers, using aircraft and dogs, and hundreds of civilian volunteers spent days searching for the teen.

Penobscot County Sheriff Glenn Ross urged parents to keep an eye on their children's online activities.
