A Pennsylvania appeals court upheld a $4.5 million jury verdict yesterday against a truck manufacturer over an accident in Coraopolis four years ago in which a six-pound fire hose nozzle became a fatal projectile.

The lawsuit was filed by two families over an August 2004 incident in which a hose dangling from a moving fire truck became stuck under a parked car, then whipped around and struck two 10-year-old girls standing on a nearby lawn.

Erin Schmidt died of head injuries and her close friend and classmate, Joeylynne Jeffress, suffered extensive injuries but survived.

The plaintiffs also include three witnesses to the accident: Erin's mother, Joyce A. Schmidt; Erin's 13-year-old sister, Lindsay; and Joeylynne's 14-year-old sister, Lauren.

A divided three-judge Superior Court panel said state law allows bystanders who witness injury to a close relative to collect damages for emotional distress under certain circumstances.

The court also ruled that Sinor Manufacturing Inc. of Clinton, Okla., which purchased at least parts of the company that manufactured the fire truck, inherited liability for the accident. Sinor is now known as Freightliner Specialty Vehicles Inc.
