Loudoun County authorities are asking for the public’s assistance finding two missing Ashburn teens they say are considered “endangered” and believed to be together, according to the county sheriff’s office.

Adam Van Alstyne, 17, and Hope A. Jager, 16, were last seen at their homes June 8 around bedtime, authorities said.

The teenagers are believed to have left together during the night and are likely driving a white1999 Honda Accord with Virginia tags ADH-4643 or XNC-1278, authorities said.

Kraig Troxell, spokesman for the Loudoun County Sheriff’s Office, said the teens left a note for their families. Troxell declined to specify the note’s contents.

“The statements weren’t really clear,” he said. “They didn’t necessarily make statements that they wanted to harm themselves, but they made statements regarding their well-being in the future.”

Van Alstyne and Jager are dating, authorities said, and are considered endangered due to the nature of the statements they made in the note.

Anyone with information about the teens is asked to contact Investigator M. Grimsley at 703-777-0475 or call the Loudoun County Sheriff’s Office 24-hour non-emergency line at 703-777-1021.
