Minivan Killer

A short skit I would like to produce in the near future.

Setting - Minivan full of people.

Plot - Every time the car passes under a tunnel, the picture goes black. Once out of the tunnel one person dies and no one can figure out who did it.

Killer is in back left seat. Back right is the first passenger to die, mid-left, mid-right, passenger, driver.

Author's Note

Not sure of a way to end the skit. Ideas are welcomed.
