RALEIGH, N.C. — Detectives from the Wake County Sheriff's Office have interviewed the girlfriend of a teen found dead late last year in a vacant home owned by the parents of one of the suspects in his death.
Court documents made public Wednesday said the four suspects in Matthew Silliman's death had been talking with the teen's girlfriend, Michelle Lippert, on the social networking Web site Facebook.
Detectives are also searching for a video taken of Silliman by one of the suspects in the hours before Silliman was last seen by his parents.
Authorities issued a Silver Alert for Silliman after he went missing. According to a search warrant affidavit, Lippert had knowledge of his disappearance but did not report it to authorities.
Four teens, Aadil Shaaid Kahn, Allegra Rose Dahlquist, Drew Logan Shaw and Ryan Patrick Hare are charged with murder. They could face life in prison if convicted.
