Charleston police make obstruction arrest in West Ashley homicide case

Antoine Donnell Alston

Charleston police have charged a man with obstruction of justice in a homicide investigation.

The victim, Richard Garfield Williams, 40, was found about 5:40 p.m. June 3 lying face down outside his house on North Avalon Circle. The area is off Orange Grove Road near Ashley Hall Road.

Antoine Donnell Alston, 27, of South Kenwood Drive in North Charleston was charged with obstruction of justice, police spokesman Charles Francis said. Police said Alston intentionally provided investigators with false information regarding the investigation.

Alston was already in jail after being arrested the day of the homicide and charged with possession of marijuana with intent to distribute. His bail on the obstruction charge was set at $75,000, in addition to the $25,000 on the previous charge.

Alston pleaded guilty to assault and battery of a high and aggravated nature in April 2014 and was given credit for the 930 days he has spent in jail since his arrest in August 2011, according to Charleston County court records.

He had previously been convicted of possession of marijuana and unlawful possession of a pistol.
