MOUNT PLEASANT -- A second suspect was arrested Thursday in last month's fatal shooting at a Ben Sawyer Boulevard condo, and police said the first man they arrested was linked to the slaying by DNA evidence.

James Gerald Pinckney, 26, of Piedmont Avenue, North Charleston, was charged with murder in the March 11 shooting death of Oscar Manuel Giron-Hernandez, also of North Charleston, at Marsh Grass Condominiums, Mount Pleasant Police Capt. Stan Gragg said. Pinckney was in jail in Berkeley County on unrelated charges.

According to court records, Pinckney was charged by Goose Creek police on Wednesday with second- degree burglary and resisting arrest.

Investigators also searched

Pinckney's apartment on Thursday, Gragg said.

On Wednesday, police charged Adrian Keith Beaton, 20, of North Charleston with murder in the case. According to the arrest warrant, Beaton's DNA was found on materials used to bind a victim inside the apartment.

Police said Giron-Hernandez, 33, was shot and killed and his wife wounded by gunfire when they walked into the apartment where three men had tied up a second man.

Beaton appeared briefly in Charleston County Magistrate's Court on Thursday. He is being held without bond at the Charleston County jail until he can appear at a bond hearing in front of a circuit court judge.

The only person to speak during the hearing was a victim witness coordinator who said Giron-Hernandez's wife was too scared to appear in court.

An affidavit filed with the court explains what police believe happened that day:

--Jose Domingo Contreras was sleeping inside Apartment 1511 at Marsh Grass when three men entered. The men had tied up Contreras when Giron-Hernandez and his wife walked in.

--The men shot Giron-Hernandez and his wife. He died and she was severely wounded. Contreras was released from the hospital later that day. Giron-Hernandez's wife was hospitalized for several days.

The affidavit says the State Law Enforcement Division processed the items used to bind Contreras and produced a DNA profile that identified Beaton. Though it is not in the affidavit, Beaton's DNA was on file with SLED because he has served time in prison. The state has a mandatory DNA policy. Samples are collected from all inmates when they enter prison.

Gragg said investigators know why the suspects tied Contreras up but declined to release the information because of the investigation.

This investigation is ongoing and additional arrests are anticipated, Gragg said.
