LOWER SAUCON TWP., Pa. -

The child killed in an accident on Interstate 78 early Wednesday morning has been identified.

The Northampton County coroner identified the victim as Ravon Robinson, 5, of Newark, New Jersey. A family member, however, spells his name Rayvon. 

The boy died of the injuries he suffered when he was ejected from the car in which he was riding, according to the coroner.

A family member told 69 News that Robinson's two-year-old sister was sitting next to him in the car, and she's currently on life-support at Lehigh Valley Hospital near Allentown.

The children were riding in the rear of the car when it left the highway went off the highway's eastbound lanes between the Hellertown interchange and the exit for Route 33, according to Pennsylvania State Police.

The driver, Nadine Walton, then tried to correct the move, but drove across both lanes of traffic and hit a guard rail. The car was then struck by a Kia Forte and Dodge Caravan, police said.

All three of Walton's passengers -- the two children and Stefany Stephans, 31, also of Newark -- were ejected from the vehicle, police said. 

Walton suffered serious injuries and was last reported to be in critical condition. Stephans was also injured.

State police said open alcohol containers were found in Walton's car.

Interstate 78 was closed for hours while police investigated the crash.
