Police say a 16-year-old girl was grazed by a bullet during a shootout Sunday morning that left two people in custody and officers searching for a third suspect.

According to St. Paul police, officers were called to the parking lot of a Cub Foods store located on the 1100 block of Clarence Street for a shooting at around 10:45 a.m.

When officers arrived, they found 17 shell casings and damage to two unoccupied cars in the parking lot.

Police say two males shot at a third male in the store’s parking lot and believe the third male returned fire.

While there, St. Paul police arrested a 20-year-old man believed to have been with the two male suspects on an unrelated warrant in Texas for weapons. While the man was with the suspects, he isn’t believed to have been an active participant in the shooting, according to St. Paul Police Department Sgt. Mike Ernster,

According to police, the 16-year-old who was injured is expected to be OK, saying the graze wound to her abdomen is considered to be minor. The girl did go to Regions Hospital late Sunday.

Officers were then led to a home on the 500 block of Minnehaha Avenue East, where they found two of the suspects — a 17- and 19-year-old — who were arrested.

Police say they’re still searching for a third suspect but haven’t provided a description or age as of this publishing.

The motivation for the shooting is still under investigation, a police spokesperson said, adding, “This was a scary situation. Cub Foods can be a very busy place on any day of the week. We are thankful that no one else was injured.”

5 EYEWITNESS NEWS spoke with a woman named Barb who happened to be walking from her car toward the store when it all unfolded.

“All I seen is a bunch of people running out, and then I started hearing gunfire,” she said on Monday, adding that she ducked for cover behind another car at that point.

“I only seen one gun, but that was enough for me, hearing them go off. You could see the smoke in the air even coming from them.”

About 24 hours after the shooting, Barb was left with heavy emotions for all involved.

“I don’t know anything about these people. I just feel for their families and their loved ones,” she said, adding, “Nobody died, which is a very fortunate thing, but it scared the living daylights out of me.”
