Police in San Antonio, Texas are calling it a robbery gone very bad.
A Good Samaritan was shot and killed trying to stop two armed men attempting to rob a Kay Jewelers Sunday afternoon.
The unarmed man was shot dead, then a second man pulled out a concealed weapon and shot one of the suspects. The second suspect ran through the mall shooting randomly.
The second suspect is still on the run.
Three people including the suspect are in critical condition. One person suffered a heart attack at the scene and a woman went into labour.
A shopper inside the mall told News4 San Antonio he heard six shots and saw people fleeing the scene. Officials have asked everyone inside the mall to shelter in place.
