The husband of a 22-year-old woman who was reported missing has told police he killed his wife in a small bus they had converted into a living and traveling space. 

Vermont State Police say Joseph Ferlazzo, 41, confessed to detectives that he killed Emily Ferlazzo on Saturday morning. Police say they seized the bus in St. Albans and a search turned up human remains and other evidence that corroborated Joseph Ferlazzo’s account.

An autopsy is scheduled Wednesday to confirm the identity of the remains and determine the cause and manner of death.

According to troopers, Joseph Ferlazzo told his wife’s family in Northfield, New Hampshire that the couple were arguing as they drove on the Bolton Valley Access Road at about 1 p.m. Saturday. He said Emily Ferlazzo left the vehicle, a camper van, at one point and began walking along U.S. Route 2.

Emily Ferlazzo was last seen Saturday near a vacation rental in Bolton. She was reported missing by her family shortly after 7 p.m. Monday.

The couple’s dog, a mixed breed named Remington, was located Tuesday at the home of a friend of Joseph Ferlazzo’s.
