DEERFIELD, Florida (CBSMiami) - Investigators say bad blood over an employeeof the month award at a South Florida Walmart store led to gunfire andcriminal charges.

According to a Broward Sheriff's Office arrest report, last month'semployee of the month at a Deerfield Beach Walmart store on SouthMilitary Trail had her car shot up by a co-worker who was angry aftershe won the award. Willie Mitchell is charged with discharging a firearmfrom a vehicle.

The Broward Sheriff's Office said surveillance video from a Walmartparking lot shows Mitchell parking next to a co-worker's earlier inDecember. A few minutes later, investigators said Mitchell rolls down aback window, fires a shot into his co-worker's car, then drives off. Theco-worker was not in her vehicle at the time.

BSO Spokesperson Veda Coleman-Wright said the shooting stemmed fromsome bad feelings after the victim won an Employee of the Month Award.

"She was announced as the employee of the month... which you would thinkthat would be something good, people would be happy for her,"Coleman-Wright said. "But there was one employee who wasn't happy."

Investigators say after the award was announced, Mitchell startedarguing with the victim about their workload. The victim told detectivesthat "during the argument Mitchell told her repeatedly, 'I'm gonna showyou.'"

Hours later, BSO says Mitchell did just that. A witness told BSO thathe spoke to Mitchell in his car while it was parked next to thevictim's. The witness said Mitchell "asked him if the victim wascurrently working, to which the witness replied yes."

BSO says minutes later the shot was fired. The victim did not want tospeak on camera, but CBS4's Carey Codd saw her car window, which hasbeen fixed.

Investigators said they're still stumped on the exact motive for the shooting.

"Perhaps (Mitchell) wanted to be employee of the month but clearlythese actions that we saw in response to this, I think we see why hewasn't chosen as employee of the month," Coleman-Wright said.

A Walmart representative told CBS 4 News that Willie Mitchell nolonger works for the company. The spokesperson also said that theemployee of the month does not receive any money or gifts. She said itis strictly a recognition from the store.
