CLAY, W.Va. -- The case of a former congressional candidate accused of shooting his roommate in the leg last week will be heard by a grand jury next month.

During a preliminary hearing Tuesday, Clay County Magistrate Court Judge Jeffery Boggs found probable cause to send the case of Hiram Carson Lewis IV, 41, to a grand jury.

Lewis is charged with malicious wounding and wanton endangerment involving a firearm after allegedly shooting Steven Bogart, 55, on June 13.

Lewis told police he shot Bogart when he barged into his home, despite repeated warnings not to do so, according to a criminal complaint filed in Clay County Magistrate Court. Bogart said he lived at the home and was shot by Lewis after a dispute.

Boggs reduced Lewis' bail to $70,000 full surety. He remained in Central Regional Jail on Tuesday.

Lewis ran as a Republican for U.S. Senate in 2006 and for state attorney general in 2004 and 2008.

Also Tuesday, the state Office of Disciplinary Counsel scheduled a hearing regarding Lewis for 10 a.m. on Aug. 7. It was not immediately clear if the meeting was regarding the charges against Lewis, or involved other matters.
