A 51-year-old man who was punched once in the head at a Summerville-area bar last week died early Wednesday.

James F. Beatty of Lieben Road in Mount Pleasant had been involved in a confrontation at Loco Joe's bar at 1115 Miles Jamison Road on Jan. 10. Deputies said that after he got punched, he fell. His head struck the concrete floor, and he never regained consciousness.

"A young lady in there got too rowdy, and he kicked her out," said Maj. John Garrison, spokesman for the Dorchester County Sheriff's Office. "She went and got a man, and he came in and punched him."

According to the incident report, both men had been drinking alcohol.

After the 10:30 p.m. incident, witnesses told deputies that the man left the bar in a black sport-utility, which they tracked to a home on Wyndham Drive.

The driver, 40-year-old David Michael Sigler of Sherwood Drive in Charleston, was arrested on a charge of aggravated assault.

But Beatty's condition deteriorated, and he died at 12:42 Wednesday morning at Medical University of South Carolina.

Dorchester County Coroner Christopher Nisbet listed the cause of death as traumatic brain injury and internal bleeding.

Garrison said Wednesday that the Sheriff's Office was "evaluating" whether to upgrade the charge.

Sigler denied being involved in an altercation at the bar, the report said.
