St. Bernard Parish Jail

A New Orleans woman spent Valentine's Day behind bars after she reportedly shot and killed the father of her child outside Walmart.

Alexis King, 20, is charged with second-degree murder in the death of her boyfriend in a parking lot outside the entrance of Walmart in Chalmette.

The victim -- who was not named -- was rushed to a hospital, where he died.

Using surveillance video, investigators identified the victim as a Walmart employee, and King as a worker at a nearby business.

King admitted to killing her boyfriend once in police custody, according to the St. Bernard Parish Sheriff's Office.

Walmart reps released a statement to the NY Post on Tuesday:

"We were devastated to learn that one of our own had passed due to this horrific act of violence. Our focus is on supporting the associates in the store during this difficult time and assisting law enforcement in their investigation. Our hearts go out to the family and all those affected by this terrible situation."
