Deputies responded to the Carolina Beach Road store Monday afternoon after loss prevention employees alerted 911 about the armed robbery.
Brewer said 44-year-old Tammy Oxendine entered the store and started filling up her cart with items, including perfume and body spray, before heading toward the exit.
When employees confronted Oxendine, she pulled out a knife and threatened them as she was leaving the store.
Oxendine is wanted on charges of robbery with a dangerous weapon, larceny, and second-degree trespassing.
Brewer confirmed that Oxendine was a former employee at the Walmart store and was likely not allowed on the property.
