The Carthage man charged with killing his wife pleaded not guilty Tuesday to one count of murder.

        He was being held at the Hamilton County jail late Tuesday for lack of a $1 million bond.

        John Broe was arraigned on charges he killed Shannon Broe, 25, who was believed to be five months pregnant. Police found her body about 7 p.m. Monday in a shallow grave alongside an Interstate 71 ramp near Norwood.

        It was about 50 yards from the ramp leading to Dana Avenue.

        How she died and whether Mr. Broe will face additional charges have not been disclosed.

        Jon Esther of the Hamilton County Prosecutor's Office said Tuesday that the autopsy has not been completed.

        If it shows Mrs. Broe was indeed pregnant, Mr. Broe could face an additional murder charge for the fetus' death.

        Mr. Broe's case now goes to a grand jury, which has 10 days to produce an indictment.

        Mr. Broe faced Hamilton County Municipal Court Judge James Patrick Kenney on Tuesday. Later, the Hamilton County courthouse was evacuated as a precaution following terrorist attacks elsewhere.

        Mrs. Broe was last seen around 6:30 p.m. Thursday, when she left her job at Seasons Retirement Community in Kenwood.

        She told her mother in a phone call she was headed to bed.

        Sharon Nolan of Milford, Mrs. Broe's mother, later reported her missing.

        Police said Mr. Broe told them he had come home Thursday night but slept on the couch.

        When he awoke the next morning, he told police, he assumed his wife already had left for work.

        A search warrant was sought so Cincinnati police can search for hair, fiber and blood samples in the Broe residence on West North Bend Road and in Mr. Broe's car, which was discovered in Northern Kentucky, Cincinnati Police Capt. Vince Demasi said.

        But Darrin Hoderlein, a Cincinnati homicide detective, said Tuesday no warrant was issued. The investigation was put on hold because officers were diverted to the federal building downtown for security after the hijackings and attacks in New York and Washington.
