FORT MYERS, Fla.- A 23-year-old Fort Myers man was arrested after an argument escalated, leaving one victim with a gunshot wound to the buttock.

Fort Myers Police arrested Joseph Webb Jr. for the crime, after interviewing the victim and his girlfriend, who witnessed the event.

The victim reported that when he arrived at 127 Bourne St. to pick his girlfriend up, she was involved in an argument with Webb, her nephew. At first, the victim thought the two were playing around, but after turning physical, it became clear that it was serious in nature.

The victim stepped in, telling Webb to leave his girlfriend alone. Webb then went to the bedroom and returned with a .22 caliber revolver. He pointed the gun directly at the victim's face and fired, but missed.

When the victim turned to run, Webb fired the weapon again, this time striking him in the upper left buttock. The victim continued running out of the house and to the neighbor's for help, all the while Webb following and yelling, "I'm gonna kill you."

The victim's girlfriend told police that the verbal argument with her nephew escalated when he grabbed her by the throat and pushed her to the ground. She stated that she was speaking with the victim on her cell phone when Webb began arguing with her again. When he again grabbed her by the throat, she removed a pick from her hair and stabbed him in the face with it. It was at this point, the victim arrived and tried to intervene. The rest of her story corroborated with the victim's account of what happened.

The victim's girlfriend did not want to press charges against Webb for the physical altercation she experienced with him.

It was discovered that Webb has two previous felony convictions in the state of Florida.
