Attorneys for Joshua Komisarjevsky (koh-mih-sar-JEFF'-ski) wanted New Haven Superior Court Judge Jon Blue removed from his trial in the 2007 murders of a mother and her two daughters.
They argued Blue repeatedly made gratuitous comments while presiding over the trial of Steven Hayes, who also was charged in the murders.
But Judge Brian Fischer denied the motion Tuesday and said Blue's statements showed no bias.
Authorities say Komisarjevsky and Hayes killed Jennifer Hawke-Petit and her daughters, 11-year-old Michaela and 17-year-old Hayley, in their Cheshire home.
Hayes was convicted and condemned to death in November.
