Margot Helen Clark, 31, was riding in a car driven by Barney Joe McCombs, 50, on Southern Glassine Drive around noon. In the back seat of the green 1997 Oldsmobile was Thomas Heverly, 51.
At 11:53 a.m., McCombs drove into the path of an oncoming log truck as he turned onto Mike Padgett Highway, Richmond County sheriff's Capt. Scott Gay said.
McCombs and Clark died immediately.
Heverly was taken by helicopter to Medical College of Georgia Hospital, where he later died.
Gay said no charges are expected against the truck's driver, Jermaine Rivers, 38, who is based in Sandersville, Ga.
"He was very cooperative," said Gay, who added there was no indication Rivers was impaired by drugs or alcohol.
Clark's 13-year-old daughter, Sarah Riffe, and close friend Michael Perry, 17, were killed the night of March 2 crossing the 4800 block of McCombs Road, which does not have streetlights, in rural Hephzibah. Kellie Adkinson, Clark's aunt, said Wednesday that the past few months have seen several family deaths, including Sarah and now Clark.
"We want to ask the community to keep our family in their thoughts and prayers," said Adkinson, who described Clark as a "good-hearted person."
Adkinson said the family isn't sure where Clark was headed, just that she was out with friends.
Clark is survived by another daughter, 15-year-old Alanna Clark; her parents, Wayne and Susan Canaday; and other family members.
Jessy McCombs described his father as a "good, faithful man" and "hardworking." He woke up Wednesday afternoon and found his father missing, then got a call from his friends about the accident.
McCombs said his father wasn't currently employed but had worked previously at Plant Vogtle and Procter & Gamble. He was also in school learning how to weld, McCombs said.
In his spare time, the elder McCombs enjoyed fishing and teaching his son how to restore a late 1960s Chevrolet Nova.
Attempts to reach the family of Heverly were unsuccessful Wednesday evening.
