MISSOULA, Mont. -

A child sex sting in Missoula involving an undercover detective posing as an adult female willing to prostitute her 12-year-old female relative has led to felony child sex abuse charges against seven adults.
    
The Missoulian reports (http://bit.ly/1ia8VcO) that six men and one woman appeared in Missoula County Justice Court Friday following arrests earlier in the week.
    
Appearing in court were 22-year-old Matthew Steven Keith, 29-year-old Jenna Elizabeth Davis, 36-year-old Chad Lee Briggs, 30-year-old Christopher Michael Cooper, 54-year-old Neal Lewis Gray, 28-year-old Justin Gale Walker and James Stewart Myers.
    
Police say the seven responded to advertisements on websites. When they arrived at a location to meet the girl they were taken into custody.
    
Missoula County Sheriff's Capt. Mike Dominick says the operation was a pre-emptive measure to protect children.
    
Preliminary hearings are set for Jan. 2.
