A Hancock State Prison inmate has been charged with stabbing another inmate to death this month.
A Hancock County grand jury this week charged Antonio Wellington Ruffin with felony murder and malice murder, according to Fred Bright, district attorney for the Ocmulgee Judicial Circuit.
He said Ruffin killed Darrell Blackwelder in the prison yard on March 8.
The autopsy showed that Blackwelder died from a stab wound to the chest, he said.
Ruffin allegedly used a shank -- a homemade knife about 5 inches long that may have been made with a piece of metal ripped off a locker.
According to the state Department of Corrections, he is serving a life sentence in a 1999 murder in Richmond County.
Bright, who presented the case to the grand jury himself, said Ruffin was angry at Blackwelder for some reason. He said Blackwelder, who was from south Georgia, was a certified paralegal who often helped other inmates with legal problems.
He said no arraignment date has been set for Ruffin.
