It was open season on pizza delivery men - those working for Domino's and Papa John's Pizza serving Montgomery Village - as the primary targets.
"He had a gun. Big gun," says Carlos Zamora, a driver for a Domino's Pizza outlet that he says had two of its drivers robbed during the spree. One was a good friend.
"He went there and this guy with a gun put him on his knee," Zamora told us. "Pointed the gun at his head and took all the money and the food."
The teenager arrested in the case lived on Mills Choice Road in Montgomery Village.
Montgomery County Police tell FOX 5 the 17-year-old was ordering pizzas to his neighbor's addresses, then leaving his home through a bedroom window, hiding behind bushes and ambushing the unsuspecting drivers.
"Most of the robberies happened at night," Zamora added. "Toward the end of the shift. And we were really scared obviously."
Police say the teen, Marcus Addison, is suspected in at least eight robberies since early June.
He was arrested late Monday night, according to police, after getting caught in a sting outside an apartment on Smoothstone Way.
"Well, it's just another low down crime," says neighbor Mike Wells. "And it's a shame. But I'm glad they caught him."
Zamora says the young man charged in the case was likely using a smartphone with a pizza app to set up the drivers.
"You can track everything," Zamora says. "When we leave, when we get there and everything. He was tracking us. By the time we get there, he knew everything. And then he just pulled the gun and take the money."
Police says they recovered a pellet gun when they arrested Addison. He is being charged as an adult - with six counts of armed robbery.
