A man suspected of driving the wrong way on an interstate and causing a fiery crash that killed five teenagers and critically injured himself is expected to be arraigned on five counts of second-degree murder.

Police say 36-year-old Steven Bourgoin crashed into the teens' car in Williston and then stole a police cruiser before crashing it into at least seven other vehicles late Saturday night. Chittenden County state's attorney TJ Donovan has said he "would not classify what occurred on Interstate 89 as an accident."

Bourgoin is to be arraigned Friday in a conference room of the hospital, where his condition has been upgraded from critical to good.

Public defenders working on his case have not returned phone calls or emails seeking comment.
