The live-in boyfriend of Lisa Ann Simmons has been arrested and charged with first-degree murder. Forty-four year old Stephen George Schleuniger is being held without bond at the Allegany County Detention Center. Ms. Simmons had been missing since September 5th; evidence found at her Browning Street home led investigators to file charges against Schleuniger. Although her body has not been found, all possible means of locating her have been exhausted. Authorities believe she is dead, and have since charged Schleuniger. The investigation is continuing by the Cumberland City Police and the C3I unit.
