A South Florida Walmart employee is under arrest after shooting up a co-worker’s car hours after police said he grew disgruntled from learning the fellow worker had been selected as the store’s Employee of the Month.

Willie Mitchell pulled up to the unidentified Employee of the Month’s unoccupied car earlier this month in the parking lot of the Deerfield Beach Walmart, rolled down his back window, fired a single shot  into the vehicle and then drove off, according to CBS4 in Miami.

“She was announced as the employee of the month which you would think that would be something good, people would be happy for her,” Broward County Sherriff’s Office Spokesperson Veda Coleman-Wright reportedly said. “But there was one employee who wasn’t happy.”

The shooting reportedly came just hours after the victim had been named the Walmart branch’s Employee of the Month. In the wake of the announcement, police told CBS4 Mitchell argued with the victim over their respective workloads and told her repeatedly, “I’m gonna show you.”

Mitchell reportedly knew the victim was not in the car when he fired the shot, having reportedly asked someone in the parking lot if she was already at work just before the incident took place.

“Perhaps [Mitchell] wanted to be employee of the month but clearly these actions that we saw in response to this, I think we see why he wasn’t chosen as employee of the month,” Coleman-Wright told CBS4.

A Walmart spokesperson reportedly said Mitchell no longer works for the company, adding the Employee of the Month award does not come with any monetary benefit other than recognition for a job well done.
