Man accused in killing of Walmart supervisor claims self-defense

A man accused of stabbing a Walmart employee to death wants the case dismissed, making the victim's family furious.

"I'm devastated, because my nephew didn't bother nobody," said Sabrina Jones.

The man accused of murdering her nephew, Devon Brown, is trying to get the case dropped. Court records filed by the public defender state Caswayne Williams reasonably believed that defending himself with force was necessary against Davon. But Sabrina disagrees.

"It's very sad. I just want justice for what he's done for my nephew."

Deputies say Davon was working at this Walmart gas station last year, when Williams, a former employee confronted him.  They say an argument occurred and spilled into the parking lot where the deadly stabbing took place.

"He needs to pay for what he has done. He took a part of us, he took a part of my heart."

Attorney Mark O'Mara calls this a self defense case, rather than stand your ground.

"It's a self defense immunity hearing. Stand your ground only applies when you have an opportunity to retreat. In this case the facts seem to show, including the video tape and prior history that he was upset and went there for bad reasons. And if that means that he's the initial aggressor, then he doesn't get any of the benefits of the Florida statute," he said.

This isn't the first time Williams has tried avoiding the case. Back in January, the court ordered him competent to stand trial, after he argued he was not. Sabrina says she'll continue to fight for Devon.

"I forgive him because that's the Christian way, God want me to forgive, but I won't forget."

The hearing takes place Tuesday afternoon.
