Dallas police announced Wednesday that two suspects had been arrested in connection with the fatal shooting of an armored car guard last month.

Francisco Montez, 24, and Genaro Rivera, 21, both face capital murder charges related to an armed robbery that took place on South Carroll Avenue on the morning of September 1.

As previously covered by The Dallas Express, David Ruback, 52, and another security guard were delivering cash to Big Jim’s Check Cashing Store when a white Chevrolet Impala entered the parking lot. A gunman dressed in black jumped out of the passenger seat and fatally wounded Ruback. The gunman then took the money and hopped back into the sedan. The driver of the sedan then sped away.

Investigators claimed Rivera was the driver and Montez was the gunman. Dallas police shared video footage of the fatal encounter.

A reward of up to $50,000 was offered by Ruback’s longtime employer, GardaWorld Cash, for information leading to the arrest of his murderers. Ruback’s family added a similar reward of up to $5,000.

Speaking to Fox 4 News KDFW, Ruback’s girlfriend, Terry Ball, shared her reaction to the news of the arrests.

“There’s some … hope that maybe we’ll have justice in this, but it still doesn’t bring him back,” Ball said. “That’s the hard part. That he doesn’t get to come home when this is over.”

She said she was still left wondering how the accused murderers could think a person’s life was worth a bag of money.

“It’s not just his life that you took. You took a life away from me. You took my future. You took a life away from his friends, from his family. You took that from all of us,” she said, addressing the suspects, per Fox 4.

As of October 19, only Rivera appeared in Dallas County jail’s online records. He is being held on a bond of $2.25 million.

Dallas has seen 204 homicide offenses and 1,896 robberies so far this year, according to the City’s crime analytics dashboard.

The Dallas Police Department has been suffering from a serious police shortage in recent years. A City report previously determined that 4,000 officers would be needed to manage crime based on the city’s population, but Dallas currently only employs between 3,100 and 3,200 officers.

Downtown Dallas has been feeling the shortage, logging considerably more crime than Fort Worth’s downtown area. As previously covered by The Dallas Express. Downtown Fort Worth is reportedly patrolled by a special police unit and private security guards.
