Moore said police are treating the discovery of the body and the stabbing as separate incidents, but he also indirectly suggested police believe the body was a victim of Courtney’s: “If we take Mr. Courtney at his word, we have concerns that there are two additional deceased persons missing.”

Moore also said that police are not ruling out that Mary Coulthard, 75, of Janesville, who has been missing from her apartment at 208 N. Main St. since Saturday, could also be a victim. Coulthard’s water bottle was found on another Rock River bridge south of the area where the woman’s body was found.

Law enforcement authorities have conducted ground, water and aerial searches of the area looking for Coulthard, Moore added.

Police believe the body found Monday was not Coulthard’s because it looked “significantly younger than 75,” Moore said. He added that police were awaiting the results of an autopsy to learn the cause of death.

Courtney, who has prior convictions for battery and disorderly conduct, was covered in blood and mud when police caught him after he ran from the scene of the stabbing, Moore said. He added that the mud was not consistent with the crime scene where he allegedly stabbed Clark.
