Police arrested Carla Rae Hague Monday and charged her with felonious assault, ABCNews.com reported Wednesday. She's likely to be charged with attempted murder and possible tampering with evidence, the Ashtabula County Sheriff said.
The sheriff's office determined Judge Charles Hague was intentionally poisoned Sept. 15 with antifreeze when he became ill and was taken to the Cleveland Clinic.
Doctors found Charles Hague to have high levels of ethylene glycol -- antifreeze -- in his system, ABCNews.com said.
"The investigation found that Judge Hague had been intentionally poisoned," the sheriff's office said in a statement.
Sheriff Bill Johnson said Carla Hague's arraignment is likely to be waived and the case will go directly to the grand jury Dec. 18 to determine whether there is sufficient evidence to file the additional charges against her.
"The investigation is just simply an investigation," Johnson said. "It is a little bit more sensitive because of him being a sitting judge, but we would handle it the same way no matter who it would be in an investigation."
Charles Hague was recovering at his home.
