Underground member David Gilbert, who was found guilty for his role in the 1981 Brinks armored car robbery in which two police officers and a security guard were murdered. In 1991, Stewart was subpoenaed to explain alternative fee arrangements with a gang member whom she had been defending on a drug trafficking charge. Stewart refused the subpoena and eventually pleaded guilty to criminal contempt in the second degree, a misdemeanor charge that would not result in her disbarment.
