YORK COUNTY, S.C. -- Authorities investigated a triple shooting that took place at a gas station in York County Thursday afternoon.

The York County Sheriff's Office responded to a call of a shooting at Exxon's On the Run store on East Alexander Love Highway in York.

According to deputies, 25-year-old Darryl Hinson Jr. shot two men in front of the gas station's door with a shotgun before walking away and shooting himself.

The two shooting victims were transported to the Piedmont Medical Center in Rock Hill and Hinson was flown to CMC Main.

It is unknown if Hinson and the two men knew each other.

The York County Sheriff's Office said the shooting did not stem from an altercation that reportedly took place at a nearby Waffle House earlier in the day.
