A judge has agreed to delay the murder trial of a Camden County father accused of killing his 3-year-old son Brendan because he felt the child had become an impediment to his relationship with a teenage girlfriend.

David Creato Jr.'s trial was scheduled to start Monday. But the judge agreed to reschedule it for Jan. 9 after Creato's attorney sought more time to obtain a report from an expert witness, a forensic medical examiner.

Creato has pleaded not guilty to murder and child endangerment charges. He remains jailed on $750,000 bail.

Camden County prosecutors have said Creato's son suffered "homicidal violence."

They say the 23-year-old Haddon Township man allegedly killed the boy last October and then reported him missing, prompting a townwide search.

Prosecutors say Creato's girlfriend had resented dealings with the child's mother.
