GREAT FALLS -- Two Great Falls men died Tuesday in a head-on collision, authorities said.
Christopher Ike Isenberg, 25, and Frank Lathan, 73, died after their vehicles collided on S.C. 99 around 3:10 p.m., according to the S.C. Highway Patrol.
Authorities say Lathan was traveling north along S.C. 99 in a 1991 Dodge pickup truck when his truck crossed the center line into the southbound lane and struck Isenberg's 2005 Kia head-on.
Isenberg was airlifted to Carolinas Medical Center in Charlotte, where he died. Lathan died at Springs Memorial Hospital in Lancaster. Isenberg did not wear a seat belt, while Lathan did, said Highway Patrol Cpl. Bryan McDougald.
Neither speed nor alcohol are believed to be factors in the collision.
Chester County Coroner Terry Tinker said a toxicology test was performed on Lathan on Tuesday night, and a toxicology test is scheduled on Isenberg today. The speed limit for the area is 45 mph.
The wreck remains under investigation.
The wreck marks the third fatality on S.C. 99 this year, Tinker said.
As of Monday, 193 wrecks on state roads had claimed the lives of 209 people, according to the state highway safety office.
During the same time last year, 227 people had lost their lives on state roads as a result of 206 wrecks.
