Police are scouring computers recovered with the explosive device found in a Franconia home earlier this month. They are looking for more information about the device itself, according to a search warrant filed on March 19.

The device, discovered by a cleaning crew in a vacant home on the 6500 block of Gildar Street on March 5, contained nails and could have been lethal, according to police. The Fairfax County Police Department's bomb squad took the bomb outside the home and disabled it. 

Along with the device, the five computers were found in a laundry room in the house's basement. Police believe the computers could contain directions on how to make bombs.
