The robbery and murder of Gardaworld security officer David Ruback happened Friday morning outside Big Jim's Check Cashing Store on Carroll Avenue.

The surveillance video doesn’t show the shooting, but it does show a gunman running off with a bag of cash. Now, police are asking for help identifying the men.

On Monday, police released still images of the men they’re looking for as well as the car they want to find.

"Possibly a Chevrolet Impala we're thinking, but we hadn't confirmed that yet because the vehicle has not been located," Dallas Police Detective Reginald Woods told FOX 4 on Monday.

The car had black rims with an open sunroof with a black antenna.

Surveillance photos show 2 suspects in guard's shooting

Two Gardaworld armed security guards were delivering cash to the store in the Baylor Meadows neighborhood, east of Downtown Dallas. They were shot by two armed suspects wearing black armor gear and carrying long rifles. One of the guards, 52-year-old David Ruback, died.

"This man didn’t have to be done like that. This was a straight ambush," Woods said. "That’s all I can say. From what I’ve seen, this was a straight ambush. He stood no chance at all."

After the shooting, the suspects took off.

"They were last seen traveling south on Carroll towards I-30 where a witness sees them turn to go west on Santa Fe and that's the last place they were seen because they almost hit a pedestrian on Santa Fe," Woods said.
