A Missouri sheriff and two deputies are accused of participating in a scheme to help a man kidnap his child.

Iron County Sheriff Jeff Burkett, deputies Matthew Cozad and Chase Bresnahan, and the father of the girl, Donald Gaston, were arrested Thursday, according to court records.

All four have been charged with conspiracy and participating in group criminal activity under a state “street gang” statute, in addition to other individual charges, according to charging documents.
