Police: Cobb County siblings killed when 17-year-old sister loses control of SUV in S.C.

Two Cobb County siblings were killed after their 17-year-old sister allegedly lost control of the family’s SUV on a South Carolina interstate, police said Monday.

Jessica Wolwark was driving a Chevrolet northbound on I-85 in Anderson County when she ran off the highway and the SUV overturned Saturday morning, according to police.

Wolwark and her mother, Natalia Anggraeni, were both wearing seat belts and were seriously injured in the crash. Two other family members died from their injuries after being ejected, police said.

Kirana "Kiki" Wolwark, 15, and 12-year-old Nate Wolwark were both killed, a family friend posted on a Go Fund Me page. The family was traveling from their Kennesaw home to Wofford College in Spartanburg, S.C., where the girls were to attend a religious retreat, according to Chrissy Concepcion, who set up the fundraising page for the family. The family does not have medical insurance, she said.

The South Carolina medical examiner was unable to confirm the identities of those killed, but family friends confirmed the names and ages of the Wolwark siblings.

“Kiki was a joy to be around, and spread her love for animals to everyone she knew,” Concepcion posted. “Nate was the perfect boy; always helpful, caring, and accepting of everyone around him.”

The driver and her mother were both taken by helicopter to a Greenville hospital, where both remained Monday. Anggraeni has a broken neck and several broken ribs, Concepcion said. Jessica Wolwark has torn ligaments in her arm, but is expected to be released from the hospital this week.

The South Carolina Highway Patrol is investigating the crash.
