CHARLESTON, W.Va. -- West Virginia's regional jail chief is concerned about what he calls a "buddy system" among correctional officers at the Western Regional Jail.

Regional Jail and Correctional Facility Authority executive director Joe DeLong said 15 correctional officers at the Barboursville jail are on suspension. Some are accused of using excessive force against inmates. Others allegedly brought contraband into the jail.

DeLong said some of the officers are accused of helping to cover up wrongdoing. That concerns him more than the use of force, he said.

Media outlets reported that DeLong voiced his concerns Monday during an appearance before an interim legislative committee.

DeLong told lawmakers that the Authority wants to install surveillance cameras in the regional jails, but that it will require a significant investment of funds.
