<p>Two teen girls accused of killing one of the girls' grandparents were denied bond on Thursday.</p><p>Prosecutors argued that Sandy Ketchum, 16, and 15-year-old Holly Harvey should stay in jail because they are flight risks and because of the severity of the crime. Fayette County Superior Court Judge Paschal English did not explain why he denied the bond in his ruling, but promised a speedy trial.</p><p>Holly Harvey is accused of recruiting Ketchum, her lesbian lover, to help kill Harvey's grandparents, Carl and Sarah Collier, both in their 70s, in their home on Aug. 2, police said.</p><p>Police say the elderly couple, with whom Harvey lived, had ordered her to stop seeing the girl and to stop using drugs.</p><p>The teens were arrested a day after the stabbing deaths at the home of two boys they had met on Tybee Island, about 230 miles away.</p><p>Prosecutors on Thursday also added the charge of armed robbery to the murder charges the girls already were facing. There was no elaboration on why the charge was added, but prosecutor Daniel Hiatt presented testimony that the girls had stolen Carl Collier's pickup truck and some jewelry from the Colliers' home.</p><p>When the girls were arrested on Tybee Island, police also found four knives _ three from the Colliers' butcher block and one folding buck knife _ that authorities believe were used to stab the Colliers at least 15 times each, said Fayette County Sheriff's Office Lt. Col. Bruce Jordan.</p><p>A family member began crying and exclaimed, "Oh God!" after Jordan explained how the Colliers were killed.</p><p>Lloyd Walker, Ketchum's attorney, said the legal system had failed his client. She has been in and out of the juvenile justice system and had even flunked drug tests with little consequence, he said.</p><p>"The evidence shows that a lot of people have failed Sandy," Walker said. "Up until now, everybody, including the state, has failed this child."</p><p>He also said she had been failed by her mother, who ignored orders that Ketchum was not supposed to have contact with Harvey.</p><p>Ketchum's eyes were puffy as she entered the courtroom. Her shackles clanked together as she occasionally wiped away tears.</p><p>Harvey rested her head on a table during the entire hearing _ only looking up to speak with her attorney, Judy Chidester. The attorney later said the girl was upset that no one testified on her behalf.</p><p>Chidester, who said police were using "misdirection" by claiming the girls were lesbians, said Harvey's mother was in prison at the time of the stabbings and that her father, a quadriplegic, had little involvement with the child.</p><p>She acknowledged even while asking the judge to grant bond that there may be nowhere for Harvey to stay. Ketchum's father, Tim, and stepmother, Elizabeth, testified that Ketchum was a victim of society and that they would monitor her 24-hours-a-day if the girl was granted bond.</p><p>Family members did not comment after the trial. One family member spit at a cameraman. Another shouted, "I love you, Sandy" as the girls exited the courtroom.</p>
