A former Unity man who told police he set fire to a mobile home following arguments with his girlfriend has been charged with arson, police said Tuesday.

Deputies with the Waldo County Sheriff’s Office arrested Addison Duong, 20, formerly of Unity, on Monday, charging him with a single count of arson in connection to the fire, according to a press release from the sheriff’s office.

Arson is a class A felony punishable by up to 30 years in prison and $50,000 in fines.

The sheriff’s office said that the arrest was the result of an investigation into the Dec. 28 mobile home fire at 10 Landry Place. No one was home when the blaze occurred around 11:20 p.m.

Unity Fire Chief David Smith said at the time that a family with infant twins lived there. Because no one was around to report the fire until neighbors noticed it, the home was fully engulfed in flames by the time firefighters arrived, Smith said.

Smith previously identified the property owners as Ralph Pagliaroli and his wife, Patricia, and said they were renting the mobile home to a relative and her boyfriend.

In an interview with Waldo County Deputy Jordan Tozier, Duong said he was upset over relationship problems he was having with his then-girlfriend and that he intentionally set fire to the mobile home, according to investigators. The fire destroyed the mobile home.

Duong remained jailed Tuesday morning at the Waldo County Correctional Center with bail set at $5,000 cash or $25,000 surety bond.

The investigation leading to Duong’s arrest was conducted in conjunction with the state fire marshal’s office, the release said.
