Since Reeves, 35, was slain in that home the night of Feb. 27, 2001, friends have tried posters and other publicity to find justice. On Sunday, they focused on another strategy.
"Help us to rest in the trust that through you justice shall prevail," family friend Anne King said in her opening prayer.
Family friend Mike Love closed the half-hour service by asking all to pray for justice.
His daughter Kori Love, 18, earlier asked everyone to "pray for justice and for a resolution of the mysteries surrounding her death."
Flames flickered as 31 people heard songs, prayers, poems and muffled sobs. A photo of Reeves was illuminated by candles on the nearby porch. Reeves' mother, Faye Reeves, embraced Robin's daughter, Hannah Neville, 13. Robin's son, Joseph Standridge, 11, stood nearby.
Family members said they will keep working for a resolution to the investigation. Hannah's aunt, Cathi Neville of Martinez, said the investigation and the $17,000 reward could still break the case.
"Somebody knows something," she said.
Her husband, Sean, said he has tried to have the unsolved case featured on a national TV show, but without success so far.
The small crowd heard some of Reeves' favorite songs, John Denver's Sunshine on My Shoulders and Tim McGraw's Please Remember Me. They listened as family friend Tricia Kennedy sang Amazing Grace.
Before the vigil, Faye Reeves welcomed visitors into her home next door, where she is raising Hannah and Joseph.
She said this year's crowd was smaller than in some years past, perhaps because the vigil date fell on a Sunday. She said no one needed to organize the event or to send reminders.
"It's just understood each year on the 27th," she said.
She said there is no doubt about whether friends will gather again on the 11th anniversary of her daughter's slaying.
"It's just understood next year, but we hope to be celebrating justice," she said.
Pat Morgan, the assistant special agent in charge of the Georgia Bureau of Investigation's Region 7 Office, said the case is not cold.
"We still have leads, and I just did an interview the other day," he said recently.
A reward is still being offered for anyone with information leading to the arrest and conviction of the person, or persons, responsible for the crime, Morgan said. Anyone with information can call the GBI office at (706) 595-2575, the Thomson Police Department at (706) 595-2166 or McDuffie County Sheriff's Department at (706) 595-2040.
