DALLAS (AP) - A female Texas trooper has been suspended amid an investigation of her videotaped body cavity search of two women along a busy highway. Department of Public Safety spokesman Tom Vinger said late Wednesday that Trooper Kelley Halleson has been suspended with pay. Results of a Texas Rangers inquiry are expected to go to a Dallas County grand jury in January. An Irving woman and her adult niece this week sued Halleson and a male trooper, plus DPS director Steve McCraw, over the July traffic stop. Angel and Ashley Dobbs say the search videotaped by a patrol car camera was unlawful and humiliating. The women say a male trooper says he saw them throw cigarette butts out a window, questioned them about drugs and summoned Halleson. No drugs were found. Copyright 2012 The Associated Press.
