HAMILTON, Ohio (AP) — A man accused of killing four family members is due back in court in Ohio.

Butler County Judge Gregory Howard could set a trial date for 37-year-old Gurpreet Singh at Thursday’s hearing. Singh has pleaded not guilty to aggravated murder charges and is being held without bond. He potentially faces the death penalty if convicted.

Singh called 911 on April 28 to report finding the four “on the ground and bleeding” in a West Chester apartment where he also lived. His wife, her parents and her aunt all had been shot in the head.

Singh’s attorney, Charles H. Rittgers, says Singh is “absolutely not guilty.”

Singh was arrested in Connecticut in July. Rittgers said the truck driver went there for a wedding.

The slayings stunned the southwestern Ohio suburban community.
