Six dollars in gas money.

That's what relatives said was behind a fatal feud that left two people dead and one man behind bars, charged with their murders.

Rick Morrocco Williams, 25, of St. Stephen is charged with two counts of murder in the slayings of Nathaniel Lonnie, 58, and Angela Ferguson, 44. They were found Monday in their apartment at 2110 Durant Ave. in North Charleston. Both had been shot in the head.

The couple were slain hours after police were at their home to take a vandalism report, according to court records and police reports.

Williams was arrested at a North Charleston residence Tuesday night, according to Spencer Pryor, public information officer for the North Charleston Police Department. Williams confessed to the killings and said he used a black and silver revolver, according to the charging affidavits.

At a bond hearing Wednesday, Lonnie's stepdaughter, Doris McCollin, pleaded with Charleston County Magistrate Priscilla Baldwin to keep Williams behind bars.

"For whatever reason," she said, "he took the life of two loving people, with no remorse."

Several other spectators burst into tears. Another relative told the judge that the slayings left six children without a mother.

At the request of a victims' advocate from the police department, Baldwin stipulated that Williams was to have no contact with the victims' relatives if he is ever released on a bond.

But the bond hearing was just a legal formality. Baldwin said only a circuit judge may set bond on murder charges. Williams is being held without bail in the Sheriff Al Cannon Detention Center.

After the hearing, McCollin said she believes she knows why the two were killed.

McCollin said her sister was Williams' girlfriend and that Williams and her sister had been staying at Lonnie's apartment on Durant Avenue for about a month.

There was tension between the two men, she said. At first they argued over a dog, she said. That argument quieted down, but then they argued over money, she said.

On Dec. 30, Lonnie was trying to kick Williams and his girlfriend out of the apartment, and he threw their stuff outside, she said.

"He said he couldn't leave because he'd put six dollars worth of gas in the van," McCollin said of Williams.

According to a North Charleston police incident report, an officer responded to the apartment about 12:07 a.m. Dec. 31.

Lonnie reported that someone had broken all the windows in his van, including the windshield, the report said.

The murder warrants accuse Williams of fatally shooting the victims about 4 a.m. Dec. 31, just hours after the incident with the van.

The warrants said police interviewed Williams' girlfriend, who said Williams had "told her that he 'shot up the place,' referring to the victims' house."

Williams has past convictions for possession of crack cocaine, criminal domestic violence and third-degree burglary, according to a State Law Enforcement Division criminal background check.
