Roger Gillett, 29, and his girlfriend, Lisa Jo Chamberlin, 31, appeared Wednesday in a courtroom in Russell, Kansas, to be served with the Mississippi warrants charging them with murder.
The Russell County couple is accused of killing Vernon Hulett, 34, and Linda Heintzelman, 38, both of Hattiesburg.
County Attorney Daniel Krug said Chamberlin waived her right to an extradition hearing, while Gillett did not.
The bodies of the victims were found during a drug investigation at a vacant farmstead near Luray, Kansas.
The family said Gillett and Hulett were cousins who grew up together in Kansas.
