It happened at the Red Wing Shoes store in the 3100 block of South Cooper, police said.
They rushed to the scene about 1:50 p.m. when workers at neighboring businesses called reported what sounded like gunfire.
When police arrived they found the deceased employee at the back of the business. The back door was jar, the front door was locked.
Late Tuesday, investigators released pictures of the vehicle -- a light-colored Tayota Tacoma pickup.
