An 84-year-old woman jailed in Montgomery County on an unrelated charge has been accused of trying to hire a hit man to kill a Montgomery County assistant district attorney and to injury the district attorney, officials said.

Dorothy Clark Canfield is charged with solicitation of capital murder and solicitation to commit aggravated assault on a public servant, said Brett Ligon, Montgomery County District Attorney.

Ligon said Canfield was an inmate at the county jail when she allegedly told other inmates she wanted to hire someone to kill Assistant District Attorney Robert Freyer, who is prosecuting an unrelated case for which she had originally been jailed.

She also allegedly said she wanted Ligon injured severely enough to put him in the hospital for two to three weeks.

Ligon said an informant told authorities about the request and an investigation into the case began in early April. An undercover officer met Canfield during a visitation at the jail and she allegedly agreed to pay him $7,500 for the attacks.

When the Texas Rangers interviewed Canfield about the plot, she confessed, officials said. The investigators had shown her pictures from an unrelated crime scene and pretended that Freyer had actually been killed. Canfield showed no remorse when she saw the photographs, officials said.

Ligon said Canfield was in jail awaiting trial because she allegedly posed as an immigration attorney and took about $51,970 from people seeking her help with their legal issues. However, Ligon said, Canfield is not an attorney and she did not help her supposed clients.

She was charged with theft between $20,000 and $100,000, court records show.

When she allegedly plotted the attacks on the prosecutors, Ligon said, she made it clear to the undercover officer that she wanted Freyer killed. Ligon said she wanted him injured so it would appear that the killing could be connected to the recent shooting deaths of Kaufman County District Attorney Mike McLelland and his wife, Cynthia, as well as Assistant District Mark Hasse.

The prosecutors' killers have not been found.

Ligon said it appeared she thought she could throw investigators off her trail if he was injured, suggesting the same person or people who killed the McLellands and Hasse were involved in Freyer's death.

Ligon said the Kaufman County prosecutors' killings have made law enforcement statewide even more vigilant and cases involving threats against law enforcement officials will be vigorously prosecuted.

"It's not open season on public servants," he said.

Canfield has lengthy criminal history. In 2009, she was convicted of Canfield was convicted of felony theft by check and served two years in the Texas Department of Criminal Justice, court records show. She was released in 2011.

She pleaded guilty to forgery and was sentenced to 10 year's probation in 1993.

In 1986, she was convicted of felony theft and sentenced to four year's probation.
