Two men were charged with double homicide a week after the bodies of Vanita Richardson and Truvenia "Bean" Campbell were found under a bridge in northwest Georgia.
Desmond Brown, 28, was taken into custody on Monday and charged with misdemeanor resisting arrest. His arrest was in connection with the investigation into the grisly murders.
Devin Watts, 36, was arrested on Tuesday and charged with counts of theft by receiving stolen property and possession of a firearm by a convicted felon.
Both suspects were charged with murder in the deaths of the stepsisters on Wednesday.
Richardson, 19, and Campbell, 31, were last seen alive on May 12.
A road crew discovered the bodies under the east bypass bridge in Rome, Georgia on May 13.
Authorities are still searching for Richardson's car, a gold 1997 Toyota Corolla with Georgia tag RTJ 6295.
The stepsisters were always together -- inseparable. Truvenia Campbell had epilepsy since birth. Richardson kept a close eye on her.
"They were very, very close. Very, very close," said Campbell's mother, Donna Campbell. She pleaded with mourners to space themselves 6 feet apart at a vigil for the victims outside Campbell's home in Rome on Monday.
