Police release images of suspects of deadly armored-car heist Friday in Old East Dallas

Authorities are asking the public’s help to find two suspects in a deadly armored-car robbery in Old East Dallas last week.

Police on Sunday released images of the suspects and the vehicle used in the heist. A uniformed guard, later identified as 52-year-old David Ruback, was shot and died at a hospital. Images showed both suspects dressed in black with black masks over their faces.

In one of the images released by police, a suspect appears to be armed with a gun and wearing body armor, gloves and white-colored shoes.

Shortly before 9:30 a.m. Friday, officers responded to a shooting in the 100 block of South Carroll Avenue, police said. Investigators learned that Ruback and his partner were making a cash delivery to a business in the area.

One of the suspects approached Ruback as the guard was walking up to the business and shot him, police said. The suspect then picked up the bag of cash Ruback was trying to deliver and drove away from the area in a white Chevrolet Impala with a second suspect, according to police.

Police have not found the suspect vehicle.

Anyone who has information about the whereabout of the suspects or the vehicle believed to have been used in the robbery is asked to call 911.
