HOULTON, Maine (NEWS CENTER) - Thayne Ormsby made a list of two people he wanted to kill, and Jeffrey Ryan was on it, according to prosecutors on the first day of the triple murder trial.
Ormsby, 22, is accused of killing 50-year-old Jeffrey Ryan, his 10-year-old son Jesse Ryan, and their friend, 30-year-old Jason Dehahn in Amity in June 2010.
He is also facing one count of arson for allegedly setting fire to Jeffrey Ryan's truck after the killings.
Ormsby has pleaded not guilty by reason of insanity.
In opening statements, Deputy Attorney General Bill Stokes said Ormsby wrote a list of two people he wanted to kill, and Jeffrey Ryan was on the list because he believed he was a "bad person."
"[Ormsby] believed the world would be a better place without [Ryan] in it," said Stokes.
The prosecutor said Ormsby thought he was acting as a vigilante when he killed Ryan, who he suspected was a drug dealer.
"Thayne Ormsby went to the home of Jeff Ryan on the night of June 22, 2010 with murder on his mind," Stokes told the jury.
What Ormsby didn't anticipate, Stokes said, was Ryan's 10-year-old son and friend being home at the time.
Stokes said Ormsby stabbed the two after he was done killing Jeffrey Ryan outside, by his shed.
"As the young boy cowered in fear, this defendant stabbed him in the back," said Stokes to the jury.
But according to defense attorneys, the facts are not that clear.
"We believe the State will provide you with more than sufficient evidence to resolve any questions of why or how these tragic and horrific events unfolded," said Defense Attorney James Dunleavy.
"The answers, however, to the questions of why and who may be more elusive," said Dunleavy.
Dunleavy did not reveal many details about the defense's case, but alluded that there will be questions about Ormsby's motive and relationship with Ryan.
"The question of what happened has more depth," said Ryan.
The state called the first of its witnesses Monday afternoon, including Dehahn's wife, Crystal, his brother, Jake, and his father.
The three witnesses testified how they found out about Dehahn's death, describing Ryan's bloody trailor the day after the murders.
According to prosecutors, the list of witnesses is about 15 pages long.
Trial is expected to last for several more days.
