HILTON HEAD ISLAND, S.C. - A judge has postponed the murder trial of three men charged with murder in the slaying of an 8-year-old Hilton Head Island boy after new evidence has come to light.

Circuit Judge Thomas Cooper has also ruled that 37-year-old Aaron Young Sr., his 20-year-old son Aaron Young Jr. and Tyrone Robinson, 38, will be tried separately.

The judge made the rulings in Beaufort on Wednesday as opening arguments were to get underway.

The new evidence consists of video and audio recordings from a Beaufort County Sheriff's cruiser. Authorities would not discuss the new evidence or why it just surfaced.

Khalil Singleton was playing outside a home when he died in the crossfire from a gunfight in September 2012.
