Authorities confirmed that at least two people were killed and 13 others were injured in a shooting at a Kroger grocery store in Collierville, Tennessee, about 30 miles east of Memphis.

According to Collierville Police Chief Dale Lane, the suspected shooter is dead from an apparent self-inflicted gunshot wound, and that there were “very serious” injuries among those taken to the hospital. Twelve people were transported for injuries, while at least one person walked into the hospital. Law enforcement searched the shooter’s car, and Lane did not say what type of weapon the shooter used. Lane said he did not know how many people were in the store at the time of the shooting but said one Kroger employee was rescued from the roof of the building.

During a press conference, Police Chief Lane said customers hid in freezers and locked offices when the gunfire broke out at about 1:30 p.m. local time, police said. One employee fled to the roof and was escorted to safety by police.
