A 31-year-old man told sheriff's deputies that a man in a cowboy hat shot him early Sunday as they argued outside a Mexican bar on Johns Island.

Ricardo Contreras of Maybank Highway on Johns Island suffered a gunshot wound that was not life-threatening. Contreras said he didn't know his assailant, who was wearing a cowboy hat, and the Charleston County Sheriff's Office has arrested no one in connection with the shooting.

According to an incident report, Contreras and his cousin had been drinking at the Mexican Cantina at 3440 Maybank Highway around 2:30 a.m. Sunday.

Contreras said he started arguing with a Hispanic man in the bar. When the altercation continued in the parking lot, Contreras told deputies that the man pushed him to the ground, stood over him and shot him in the knee with a black handgun.

The gunman then chased Contreras' cousin, 24-year-old Francisco Contreras of Maybank Highway, behind the business and shot twice at him but missed, according to the report.

Three shell casings were found around the building. The caliber of the shells was not released.

The cousins told deputies that the gunman left the scene with his son, who also had a gun, in a red Saturn sport utility vehicle, but that they did know the men.

Contreras, who was taken to Medical University Hospital, described the gunman as in his 50s, about 5 feet, 6 inches tall and 185 pounds.
