Chicago ? A white supremacist awaiting sentencing for soliciting the murder of a federal judge denied that his supporters were involved in the slayings of her husband and mother, saying in a statement Thursday, “I totally condemn it.”

“There is no way that any supporter of mine could commit such a heinous crime,” Matthew Hale said in the statement released by his mother after her weekly telephone call to him at Chicago’s Metropolitan Correctional Center.

U.S. District Judge Joan Humphrey Lefkow arrived home after work Monday to find the bodies of her husband, attorney Michael Lefkow, 64, and her mother, Donna Humphrey, 89, in the basement, shot multiple times.

Chicago police were not discussing the investigation Thursday, but members of area anti-hate groups said investigators met with them about the killings. Police have said white supremacist groups are just one avenue of their investigation into the slayings.

Authorities are analyzing evidence from the home and neighborhood, including a broken window with a fingerprint, a bloody footprint and cigarette butts.

Authorities released sketches late Wednesday of two white men described as “persons of interest” who were seen near Lefkow’s home the day of the killings.

The shootings came a month before Hale was to be sentenced by another judge for soliciting an undercover FBI informant to murder Lefkow after she ordered him to change the name of his extremist group as part of a trademark lawsuit.
