A group of students at a nearby massage school said they heard the commotion.

"We were outside. Everybody was coming in front of the school having a conversation like we always do," said student Chris Robinson. "We just heard two gunshots and then our teachers grabbed us and told us to get inside."

Detectives said they are canvassing the area: speaking with witnesses and reviewing surveillance video to help identify the suspects. As of Monday night, they said they don’t have a description of the suspects or the getaway vehicle.

Another security guard was in the armored truck at the time of the shooting. That guard wasn’t injured.

Armored car robberies are reportedly common in the Houston area. In March, three men ambushed an armored car, killing one of the guards. The scenario was similar in the sense that one guard was in the truck, while the other was  servicing the ATM.
