Detectives and officers determined that the two suspects in the murder are the same suspects that robbed an Auto Zone at 645 Dacula Road in Dacula Monday night.

Store employees told the officers that one of the suspects walked into the store and demanded cash while pointing a gun at them. He then left he store in a black car.

Officers eventually tracked down the suspects’ car where it crashed on La Maison Drive about 3 miles from the Auto Zone. Officers searched for the suspects but couldn’t find them.

On Tuesday, authorities said they took both men into custody.

The suspects are facing armed robbery and murder charges against Cosme. Both Norah and Robertson have other outstanding warrants.

The FBI is still offering a reward of $15,000 for information leading to the arrest of the suspects involved in this crime. Tipsters interested in the reward are encouraged to call the FBI at (770) 216-3000.
