Two former Vernon County corrections employees have been charged with delivery or possession of marijuana at the county jail. Sheriff Ron Peckman says interviews and surveillance footage from the jail camera have led to felony charges against the two former corrections officers, one inmate and a civilian.

Inmate Bob Beisly, 38, and civilian Joanna Roberts, 28, are from Richards.

Former guard Colby Prough, 39, is from El Dorado Springs. The other former guard, James Tumm, 23, is from Nevada.

Police are still looking for Roberts.
