At least six of the eight people injured in a five-car wreck that killed two people on Interstate 985 near Oakwood on Sunday night have been released from the hospital.

Joshua Gravely, 31, and Mary Lancaster, 25, both of Whitesburg; Amalia Lara, 35, Isabel Rodriguez, 19, Heidi Rodriguez, 16, and Genesis Rodriguez, 11, all of Flowery Branch, were released from Northeast Georgia Medical Center in Gainesville as of Monday afternoon.

William Robinson, 33, of Buford was listed in satisfactory condition at Northeast Georgia Medical Center.

Children’s Healthcare of Atlanta said it didn’t have Emmalee Miles, 8, of Buford listed in its system as of Monday afternoon. She was transported to one of CHOA’s campuses Sunday night for what state patrol called precautionary reasons.

“This investigation will be extensive due to the number of vehicles involved to assure the investigation is done thoroughly and accurate,” Georgia State Patrol Sgt. 1st Class Anthony Coleman wrote in an email Monday. “The (Specialized Collision Reconstruction Team) part of the investigation will take several more days, and until it is completed, we will not be releasing any other information until all facts can be supported by the investigative findings.”

Georgia State Patrol Sgt. Auston Allen said Sunday it was a “chain reaction” crash with the largest impact between two Ford F-150s at the back of the line of cars in the left lane near exit 16.

Driver Virginia Hiscock, 66, and front-seat passenger William Hiscock, 55, both of Whitesburg, died in the wreck as they were in the next-to-last car in the line of five vehicles. Both were wearing seat belts, and it wasn’t raining at the time of the crash, state patrol said. The wreck happened when “traffic in front of all vehicles slowed and stopped,” state patrol wrote in a Sunday email to The Times.

Driver Genevieve Carroll, 51, of Tallahassee, Fla., had three passengers in her GMC Yukon that was second in the line of cars: Anelia Carroll, 20, Corinna Carroll, 16, and Aiden Carroll, 12, also all of Tallahassee. All four were uninjured.

Angela Kisebwe, 22, of Gainesville was in the first of the line of cars, a Nissan Versa, and was uninjured.

I-985 North near the wreck was closed for about four hours after the crash happened about 5:10 p.m. Sunday.
