D.C. police have made a second arrest in the death of an 18-year-old teenager who disappeared from D.C. last summer.

Police have charged 17-year-old Johnnie Sweet as an adult with felony murder in the Aug. 2, 2010 kidnapping and slaying of 18-year-old Latisha Frazier. Latisha's body has not been found.

Last month, another suspect, Brian A. Gaither, 23, was charged with second-degree murder in Frazier's disappearance. Police said she was assaulted during a dispute in the 1700 block of Trenton Place SE, and ultimately murdered.

According to charging documents, witnesses were with Gaither when he choked the teenager and then three women beat her to death.
