Update: The Tri-State Airport (Huntington, WV) reopened after a ten-hour closing when subsequent chemical tests proved negative although both the airport security checkpoint machine and a canine team tested positive. The Pakistani woman was very cooperative according to officials, and she was taken from the airport at 5 p.m. by federal authorities.

Transportation Security Administration spokeswoman Amy von Walter revealed that screeners at Tri-State Airport in Huntington, W. Va., have discovered two bottles of liquid that tested positive for explosive residue in the carry-on of a 28-year-old Pakistani woman. The Pakistani woman, a Huntington resident (earlier a resident of Jackson, Michigan), had purchased a one-way ticket to Detroit via Charlotte. According to Jeff Killeen, an FBI spokesperson, the woman was at the airport but had not been arrested. Albeit unclear, it seems apparent that she was being detained and questioned.
