Minivan flips on western Pennsylvania interstate; 6 killed

After the van came to rest, it was hit by an oncoming car, whose driver was treated at a hospital and released shortly after the Interstate 90 wreck on Saturday, said state police Cpl. Kevin Havern.

The sole survivor in the minivan also was treated at a hospital and released. The cause of the crash was under investigation.

The van was carrying a group of computer programmers from India and their wives on vacation. The software writers worked for Troy, Mich.-based Syntel Inc., an information technology contract services provider, said Jonathan James, vice president for marketing and investor relations.
