CHEYENNE, Wyo. (AP) - Possible traces of explosives in a delivery truck prompted authorities to shut down the entrance to the Wyoming Air National Guard base for almost two hours. A major thoroughfare in front of the base also was closed. No explosive devices were found.
The incident began around 11:30 a.m. Thursday. Guard spokeswoman Deidre Forster says the truck was delivering an antenna to the base. A routine chemical test came back positive for possible explosives residue on the truck's gear shifter and on the driver's hand. Forster says the Federal Bureau of Investigation questioned the driver. The base entrance and Dell Range Boulevard were reopened at 1:15 p.m.
