A Sagaponack man who admitted to torching a $34 million oceanfront mansion on Dune Road in Bridgehampton last year will spend a year in a psychiatric facility after reaching a plea deal.

David Osiecki pleaded guilty to arson Tuesday before Judge Fernando Comacho at Suffolk County Court. In exchange for his plea, prosecutors said the 65-year-old arsonist will undergo a psychiatric evaluation and a year’s probation in an inpatient psychiatric facility.

“The victim of the arson is amenable to this disposition,” District Attorney Thomas Spota said. “If and when the defendant completes his psychiatric hospitalization, he will then serve five more years of probation with mental health conditions.”

Authorities said that in April 2014 Osiecki torched a 1,600-square-foot mansion with seven bedrooms and 8.5 bathrooms reportedly belonging to a fellow developer.

If Osiecki violates probation during his year in a residential psychiatric facility, the court can potentially sentence Osiecki to up to 15 years in prison.
