BURLINGTON (AP) - A man on federal death row for his role in the 2000 abduction and killing of a Vermont woman is asking to have his conviction overturned in part because his lawyers say a juror improperly collected information about the case.

Donald Fell's attorneys are expected to ask a federal judge in Burlington on Tuesday to overturn his 2005 conviction.

Fell was convicted of the car-jacking death of 53-year-old Terry King. She was abducted as she arrived for work at a Rutland supermarket and later killed in New York.

In his appeal, Fell claims one of the jurors who sentenced him to death made an unsanctioned trip to Rutland where he examined the locations where the crimes took place and then told other jurors about what he'd seen.
