A Montgomery County jury indicted an 84-year-old woman on two counts of criminal solicitation.
Dorothy Clark Canfield, of Willis, was indicted Wednesday on solicitation to commit capital murder and solicitation to commit aggravated assault on a public servant.
According to authorities, Canfield planned to have Assistant DA Robert Freyer killed, and DA Brett Ligon injured.
Canfield is accused of targeting Freyer because he was the chief prosecutor of her pending theft case, and she allegedly wanted Ligon hospitalized in order to "distract the prosecution" of her theft charge.
Authorities say they learned of Canfield's alleged plot while she was in Montgomery Co. Jail.
A confidential informant gave Canfield the contact information for an undercover investigator with the Harris Co. DA's Office, who authorities say met her at the jail.
If convicted, Canfield faces a prison term of up to 99 years or life for the solicitation to commit capital murder, and a two to 20 year prison term for the solicitation to commit aggravated assault on a public servant.
Canfield is currently being held in the Montgomery Co. Jail without bail.
