A frightened young woman’s descriptions of being held captive and sold for sex at drug houses and motels over the past year has led to several arrests in what’s believed to be Spokane County’s first human trafficking case. Lawrence Dean Johnson, 43; Johnson’s wife, Dina K. Tellez, 43; Christopher G. Foster, 33; and Shanell L. Haddon, 28, who is Foster’s girlfriend, are in the Spokane County Jail as prosecutors consider formal charges against them.
