A brother and sister are accused of committing five armed robberies since October 18.
Three of the robberies occurred at the Dollar General at 107th Avenue and Indian School Road. Police say Stephen Nunez and Cecelie Monique Suazo would enter the stores armed with a handgun, a long knife, tire iron, and brass knuckles.
They would reportedly take money from the cash register, stealing nearly $1,400 in total.
No one was injured during any of the robberies.
Police say clothing descriptions and the getaway vehicle from each robbery, a black Dodge Durango, were the same.
On November 19, police spotted the Durango in an area they were patrolling, near 35th Avenue and Camelback Road. The Durango sped away after robbing the Subway restaurant.
Police pursued the vehicle to the parking garage at the Banner Estrella Medical Center.
Police sealed off the garage but saw another car leaving the garage. Nunez and Suazo were spotted in the back seat of that car.
Police say Suazo admitted that she and her brother committed most of the robberies. She also said she called to have their parents meet them at the parking garage.
Nunez and Suazo have been charged with 14 counts of armed robbery and aggravated assault.
