Two District men already facing charges in the August 2010 killing of an 18-year-old woman were indicted Wednesday, authorities said.

Brian Gaither, 23, was indicted by a D.C. Superior Court grand jury on charges of first-degree felony murder, first-degree premeditated murder and obstruction of justice in connection with the death of Latisha Frazier, according to the U.S. Attorney’s Office.

Johnnie Sweet, 17, was indicted on charges of first-degree felony murder and first-degree premeditated murder.

Gaither had been charged with second-degree murder in the case in January. In February, Sweet was charged as an adult with felony murder (kidnapping).

Authorities have detailed how they believe Frazier was killed in court papers. Sweet lured her to his apartment and ordered his friends to beat and choke the woman before trying to dismember her in the bathtub, court papers said.

Her body has never been found.

According to the documents, Sweet told detectives that he suspected Frazier, 18, of stealing $200 from him. Sweet told his friends he was going to invite Frazier, a single mother of a 3-year-old daughter, over to his apartment in the 1700 block of Trenton Place SE.

The case remains under investigation, authorities said. A total of six people were arrested in the case, and four have pleaded guilty. One of those, Laurence Kamal Hassan, is scheduled to be sentenced for second-degree murder in January.

Sweet and Gaither have been in custody since their arrests and have a hearing scheduled for Thursday, authorities said.
