The FBI announced on Tuesday that they discovered the cell phone of Alexis Murphy, a Virginia teenager who has been missing since last month, according to the Washington Post.
Federal officials did not provide any information regarding how the phone was found.
A Facebook page dedicated to finding the missing teenager posted part of the FBI statement.
"The FBI has issued a statement: 'One of the cell phones found did belong to Alexis. The location of where the cell phone was discovered will not be disclosed due to the ongoing, sensitive investigation,'" the Facebook post read.
Murphy, 17, was last seen by her family on Aug. 3 after she left home to shop in Lynchburg. Three days later, her car was discovered in the parking lot of a multiplex in Charlottesville.
Randy Allen Taylor, 48, was arrested on Aug. 11 after authorities found a strand of Murphy's hair in his camper and has since been held without bond. Taylor claims he is innocent.
On Sept. 24, a grand jury will meet to decide whether or not Taylor should be indicted.
Taylor said he ran into Murphy on the last day she was seen at a gas station, where he asked her if she could help him find a drug dealer. His lawyer, Michael Hallahan, alleges that the two met a month ago when Murphy approached Taylor at a car wash he was working at when she noticed he was smoking marijuana.
Hallahan also said that while Murphy was at his camper on Aug. 3, she and another unknown man -- described by Taylor as a black male in his 20s driving a 1990s sedan and 22-inch rims -- left in separate cars.
Murphy's mother, Trina, doesn't believe a word of Taylor's alibi and called his description of the unknown man "stereotypical."
"Of course it would be a black man with cornrows and 22s. Come on," she said.
Billy Mays, an investigator with the Nelson County Sheriff's Office, said the case has gone from a missing person search to criminal investigation.
