The bus was headed from Spring Valley, N.Y., to a Bible study session in Newark when police say it hit the bus, which was carrying no passengers, on the Exit 159 ramp in Saddle Brook Tuesday.
State Police Sgt. Brian Polite tells The Record newspaper it's too early to say whether the heavy passenger load contributed to the crash. Polite says the van swerved into the lane the bus was in, struck the bus and rolled over.
The bus driver was not injured.
The crash killed Velma Castro and critically injured four others in the van.
