Twenty-five-year-old Ian Frey of Ellwood City is charged in Lawrence County with criminal homicide and first-degree murder in the death of 38-year-old Keith Knox of Wampum.
Authorities say they were ejected after fighting inside Weisz's Hazel Manor Restaurant and Lounge in Ellwood City shortly before 2 a.m. Saturday.
Lt. David Kingston says Frey got into his car and Knox walked up, opened the door and began punching him, and Frey fired four shots with 9 mm handgun. Kingston says all of the shots were fired within the car.
A listed number for Frey could not be found Sunday and it was unclear whether he had an attorney.
