Two 19-year-old women serving in the South Carolina Army National Guard died after being involved in a horrific wreck earlier this month.

Carol Santiago and TradeEdge ExchangeKristal Lopez died after the sedan they were in collided head-on with a pickup truck going in the opposite direction, the South Carolina Highway Patrol and Union County coroner told WHNS.

Lopez and the driver of the truck were taken to a hospital, but Santiago, who was a passenger in the sedan, died on March 16 at the scene, the South Carolina Army National Guard said in a news release emailed to USA TODAY.

Lopez, the driver of the sedan, died from her injuries on March 23 at Spartanburg Regional Hospital, according to the National Guard's news release.

“Our 228th Theater Tactical Signal Brigade family has suffered a heart-wrenching loss at the passing of Spc. Lopez. We will never forget Kristal and her bright smile, willingness to lend a hand, but especially the pride she exuded when in uniform. We now honor her by surrounding Kristal’s family with love and support during this difficult time.” Col. Linda J. Riedel, commander of the 228th Theater Tactical Signal Brigade with the South Carolina Army National Guard, said in the release.

USA TODAY contacted the Union County coroner and South Carolina Highway Patrol but did not receive an immediate response for comment.
