Balfour, the 27-year-old brother-in-law of the Oscar-winning actress, had been incarcerated at Stateville Correctional Center for a parole violation. He was transferred to Chicago police custody after being served an arrest warrant, the Chicago Tribune reported. Balfour was moved to the Wentworth Area, pending charges drawn up by the Cook County State's Attorney's Office, the newspaper said.

The estranged husband of Hudson's sister, Julia, allegedly owned a gun matching the one used in the Oct. 24 triple slayings, the report said.

He is to have another parole violation hearing Wednesday, the Tribune said.
