BRUNSWICK, Ga. -- A Georgia man charged with killing his father and seven others inside the mobile home they shared plead not guilty today.

Guy Heinze Jr. entered his plea during an arraignment hearing before Superior Court Judge Stephen Scarlett in Brunswick today.

The 24-year-old suspect has been jailed since September 2009, a few days after Heinze alerted police to the killings when he dialed 911 and sobbed: "My whole family is dead."

Prosecutors are seeking the death penalty but have released no motive. The victims were all bludgeoned to death.

Judge Stephen Scarlett is a new judge for the case. It had been assigned to Superior Court Judge Amanda Williams.

Williams resigned last year to settle civil ethics charges by a state agency that were unrelated to Heinze's case.

Today, Judge Scarlett said there are items that still need to be tested before they can be entered into evidence. Attorneys have until March 9th to give the court any additional items that need to be tested.

Defense attorneys have sixty days to file any motions per the judge and no trial date has been set.

First Coast News attempted to speak with Heinze's family members after his arraignment, however they said, "No comment."
