Authorities are investigating a late-night fire at a James Island night spot where deputies responded to a triple-shooting last month.

Crews from Charleston and James Island fire departments responded to the Key Club on Fort Johnson Road just before midnight Saturday.

The building was empty, in part, since the owner has been trying to shut the business down.

Charleston Assistant Fire Chief Raymond Lloyd said arson is a likelihood. "We suspect it was possibly set by a person or persons unknown," he said Sunday.

The fire was in the back of the building in an area used as a dressing room off of a stage, Lloyd said. Damage was not considered extensive, he said.

Early in the morning of March 28, Charleston County Sheriff's deputies responded to reports of a triple-shooting at the club that allegedly followed a verbal altercation.

Witnesses reported a man drew a small pistol and began shooting erratically. Three victims were struck by bullets, but none suffered a life-threatening injury.

The night spot also is near the site of a January 2009 shooting that deputies described as a drug deal gone bad.

A 23-year-old man was killed in a hail of multi-firearm gunfire in that incident.

A man identified as the property owner said Sunday that he is in the legal process of getting the club shut down so he can turn the property over to his church.
