No arrests have yet been made in the murder of 19 year-old Brittney Fox but Cherokee County Sheriff David Groves said investigators are not giving up on the Coffeville girl.

“It’s been pretty active as far as the investigation goes,” he said. “Every week something’s being done.”

Fox’s body was found in a ditch along Bagdad road near Downstream Casino Sept. 22, 2009.

“It’s a complex investigation, it’s a complex situation,” Groves said. “At this time the investigation is ongoing and will be until all the questions have been answered.”

One week after the body was found officers had set up a roadblock to question drivers who regularly traveled the road where Fox was found in hopes they might have seen something.

In addition, the Tri-State Major Case Squad was activated in this case, which brings law enforcement assets to bear from agencies in Kansas, Missouri and Oklahoma.

Groves said this is not yet a cold case even though no arrests have been made and no suspects named.

“Obviously I wished by now we’d made an arrest,” he said. “There’s more investigating to do and each week there are new leads — and that’s promising.”
