COLUMBUS, Ohio (WCMH) – A man accused in a deadly shooting in Columbus that killed a Girard man went before a judge for the first time Monday.

Keimariyon Ross, 18, was arrested and charged with murder, accused of fatally shooting 21-year-old Kevin Sobnosky of Girard, Columbus police said.

It happened last month at a Sheetz station in northeast Columbus.

Prosecutors revealed in court Monday that surveillance video showed a shootout between the two groups of people. Police say that video identified Ross as the one who shot Sobnosky.

Prosecutors say Sobnosky, who was hit in the head with one of the gunshots, arrived at Ohio State East in critical condition and was flown by medical helicopter to OSU Main where he died later that day.

Police say four men between 18 and 21 years old were in a car and driving near the Sheetz store at the 1400 block of North Cassady Avenue, near Airport Drive, when shots were fired at the vehicle from the parking lot. Sobnosky was hit by one of the shots and died the next afternoon.

Sobnosky was visiting Columbus with the other three men. Denner said Sobnosky was a valedictorian at Girard High School and a member of the dean’s list at Youngstown State University.

Police found 20 shell casings at the scene, where multiple people were reportedly firing guns. CPD listed up to 12 persons of interest during the investigation.
