A Maine man used a fake Facebook account to lure a teenage girl out of her house. Although he originally intended to “be the hero” by staging her kidnapping and then rescuing her, he ultimately ended up killing her, according to a state police affidavit.

Kyle Dube, 20, was indicted Wednesday for the kidnapping and murder of Nichole Cable, a 15-year-old girl, the Associated Press reports. Cable’s body was discovered in a wooded area of Old Town, Maine, a week after she went missing.

In a Maine State Police affidavit released after Dube was indicted, Detective Thomas Pickering explained the events that led to Cable’s death. According to Pickering, Dube told his brother that he used a fake Facebook page to lure Cable out of her Glenburn home, not far from where her body was discovered in Old Town. He then allegedly waited in the woods, wearing a ski mask.

When Cable walked by, Dube sprang out of his hiding spot, restraining the high school sophomore with duct tape and placing her in the back of his father’s pickup truck, the affidavit continued. Later, when Dube realized that Cable had died, he dumped her body in the woods and covered it with branches.

Authorities have yet to reveal the manner in which Cable was duct- taped, AP reports. A local medical examiner’s office is still examining the official cause of her death. According to Detective Pickering’s testimony, Dube told his brother that he had "intended to kidnap Nichole and hide her; that he would later find her and be the hero.”

Dube’s attorney, Stephen Smith, had originally argued for the affidavit to be withheld, claiming that the information was a threat to Dube’s security in jail, the privacy of his relatives, and his right to a fair trial, AP reports. Justice William Anderson had ordered the affidavit to be sealed until his indictment was made public.

Cable was initially reported missing on May 13 by her mother, AP reports. The 15-year-old had left the house to meet up with a friend the previous night but hadn’t returned. Later, police interviewed Bryan Butterfield, a friend of Cable’s, who claimed that he suspected Dube of setting up a fake Facebook account under his name. According to Butterfield, Dube had previously attempted to sleep with Cable, but she had spurned his advances.

Authorities later determined that Cable had engaged in frequent contact with the fake Butterfield Facebook account, and that the person had repeatedly asked to meet with her. According to the affidavit, Cable finally agreed to meet with him on the night she went missing, after he offered to give her marijuana.

With the cooperation of Facebook officials, Maine state police were able to trace the fake Butterfield account to Dube. Later, Dube’s girlfriend, Sarah Mersinger, told police that he had told her where Cable’s body was hidden. Dube’s brother, named Dustin Dube, then revealed further information to police.
