RICHMOND HEIGHTS, Mo. – Police said they've tracked down the people who opened fire in the St. Louis Galleria Mall parking lot.

Police said workers at Nordstrom followed three shoplifting suspects into the parking lot around 2:30 p.m.

Officers said when the suspects were walking to their car, another man in a silver car pulled up and fired two shots at the suspected shoplifters.

All of them then sped out of the parking lot.

About an hour later, officers in Jennings spotted an SUV they believe was involved in the incident.

Police arrested a 15-year-old boy but two other suspects ran away from the SUV.

Officers are still trying to track those suspects down.
