The Lehigh County coroner's office said Friday that 17-year-old Zach Alai of South River, N.J., died in the collision between a car and a tow truck.
Alai was one of three passengers in the car driven by 22-year-old Nicholas Gustafson of Lowhill Township. Police say Gustafson ran a stop sign and was hit by a tow truck hauling a box truck.
Gustafson, Alai, 23-year-old Michael Bruno of Catawissa and 22-year-old Cecilia Besecker of Dallas, Pa., died in the accident Thursday in rural Heidelberg Township.
The tow truck driver, 58-year-old Charles Oswald of North Whitehall Township, also was killed.
Oswald's passenger is hospitalized with minor injuries.
