BURLINGTON, Vt. (AP) — Prosecutors say a woman has received a 15-year prison sentence for her role in a deadly fire in Vermont in 2015.

The U.S. attorney's office says 47-year-old Tammy Wilder was sentenced Monday on a charge of conspiracy to commit robbery stemming from fire in Northfield, Vermont. She was also sentenced for her role in making a place available for storing, distributing, and using controlled substances in 2014.

She was ordered to pay back over $620,000.

Court records say she was part of a group that intended to rob Efren Serrano of drugs and money. Prosecutors say three of them drove to his apartment and doused him and 22-year-old Brittany Burt with gasoline and lit them on fire. Burt died of smoke inhalation; Serrano was seriously injured.

One group member received a 24-year prison sentence.
