Four men suspected in a series of pizza delivery driver robberies were indicted on conspiracy charges Wednesday.

Christopher Teon Fults, Kevonta Dewayne Reynolds, Ra’Shawn Jones and Roosevelt Jones IV were indicted by a Bell County grand jury on charges of conspiracy to commit aggravated robbery.

The four men were arrested in August after police received a tip from a Domino’s Pizza restaurant that recognized a number used to place an order in a previous robbery. The tip led police to set up surveillance outside a house in the 600 block of Bellaire Drive in Killeen. There, they observed the four men approaching the home. When the men spotted the officers, they walked toward a sport utility vehicle parked nearby. Police detained the men and found a cell phone matching the number used to place the order along with a semi-automatic handgun and pepper spray.

The four confessed to police their involvement in several pizza delivery robberies in the area. The men range in age from 17 to 20.
