Lisa Gartner reports:
An external hard drive containing personal information on as many as 1,234 Prince William County elementary school students has disappeared, prompting investigations by the school system and the police department.
The hardware housed names and addresses of Glenkirk Elementary students, as well as the names of their classroom teachers. It also stored grades students had received and screening information for student services.
Updated: Thanks to Sang for pointing out that the drive was located (see Comments, below)
