The warden of the Maryland Correctional Institution at Hagerstown has resigned under pressure in the midst of a state investigation into allegations that inmates at the facility were kicked and beaten while shackled.

Embattled Warden James P. Tinney III, faced with a quit or be fired ultimatum from State Corrections Commissioner Jon Galley, said Friday he had handed in his resignation.

The move came on the heels of an announcement that four guards would be fired and four more suspended in connection with the alleged beatings.

Galley said the removal of Tinney had nothing to do with the probe in the alleged beatings of six handcuffed inmates, and said he would hold a news conference Monday about that investigation.

Meanwhile, two high-ranking MCI corrections officers, Maj. Irvine Clingan and Lt. Clyde Moser, said Friday they expect to be two of the guards fired on Monday in connection with the alleged beatings.

Both have repeatedly denied the incident took place.

Attorney Ed Davis, who represents the guards accused of beating the handcuffed prisoners, made the announcement that corrections officials planned to take disciplinary action against the eight guards.

The expected firings and suspensions of the eight guards drew about 100 angry guards to a demonstration in front of the state corrections headquarters in Towson Friday.
