CONYERS, Ga. (CBS/WGCL/AP) Police have charged Tasmiyah and Jasmiyah Whitehead, a pair of 16-year-old twin girls, with murder.
Conyers Police arrested the girls Friday following an investigation that began in January, when the girls' mother was found dead.
The two are charged as adults with the murder of Jarmecca Whitehead, who was found stabbed to death in her home on Jan. 13.
Conyers police chief Gene Wilson says authorities suspected the pair early on.
According to CBS affiliate WGCL, the two arrests were made after evidence found at the crime scene was processed by the Georgia Bureau of Investigation. This evidence directly linked Tasmiyah and Jasmiyah to the murder of their mother, the Atlanta station reports.
The girls, who were 15 at the time of the murder, told police that they came home and found their mother dead, according to WGCL. The teens flagged down sheriff's deputies for help after they said they made the discovery.
Police said the mother was found stabbed in the back.
Wilson says authorities know of no motive for the crime.
