HOULTON, Maine (NEWS CENTER) -- Jurors watched a police recorded confession, in which Thayne Ormsby admitted to, and described in graphic detail, three murders in Amity in June 2010.
Ormsby, 21, is accused of killing Jeffrey Ryan, 55, Ryan's son, Jesse, 10, and their friend, Jason Dehahn, 30.
He has pleaded not guilty by reason of insanity.
In the confession, taped on July 2, 2010, Ormsby said he planned to kill Jeffrey Ryan for days, and the other two victims were "perfectly innocent."
Before getting into the details of the deaths, Ormsby wiped his eyes, saying, "This is the first time I've cried."
Ormsby told police he thought Ryan was a drug dealer, and was responsible for hurting a lot of people in his life.
"Even though I never met him, he's a part of my life," Ormsby said to detectives. "He's the reason parts of my life are missing."
Ryan had a child with Ormsby's friend, Tamara Strout, and knew Orsmby's mother, Maria.
Ormsby told police he hoped to "break the molds of society" by ridding the world of a "bad person."
"He was nice to me, which was strange," said Ormsby. "But I did have it out for him."
He planned to kill another man, who he believed to be a drug dealer, after killing Ryan.
He didn't plan on killing Dehahn or the 10-year-old boy.
"I didn't want to kill them, but I didn't want to get caught for murder," he said.
In graphic detail, Ormsby told police how he committed the murders on June 22, 2010.
He said he first stabbed Jeffrey Ryan by his shed, and Ryan asked "Why?" as he was dying.
"At this point I'm in a mode," said Ormsby. "I'm scared, and I have to finish what I've started. It was a job."
He then stabbed Jason Dehahn, who was on the couch inside, playing video games with Jesse.
Ormsby said he then chased the 10-year-old into his bedroom, where he found him hiding behind his door. He said all Jesse said was he was scared.
Ormsby then ran after Dehahn and continued to attack him until he died in a ditch.
When detectives asked him where he learned to kill, Ormsby said he read literature about assassins.
He retold a story of Byzatine Emperor in Damascus who faced Islamic assassins, citing this as his inspiration.
"Somewhere in the subconscious of my mind, I've trained myself to be an assassin," Ormsby told police.
When police asked him what they should do next, Ormsby replied: "You need to arrest me first, for starters."
Ormsby described the murders as "premeditated."
The testimony came after the defense made a motion for a mistrial, saying the jury was "tainted."
The Judge questioned every juror about the dismissed alternate juror who attempted to shake Prosecutor Bill Stoke's hand Wednesday, saying he was doing a great job.
Of the 14 remaining jurors, eight said they heard the juror make one or more comments about his affinity for Stokes.
None of the jurors reported it.
Ormsby's attorney, Sarah LaClaire, said this incident, along with the alleged jury tampering on Tuesday, is further proof that Ormsby cannot get a fair trial in Aroostook County.
The Judge denied the motion for a mistrial.
The prosecution has rested its case in the first phase of the trial.
Closing arguments are expected to begin Friday.
The second phase of the trial, the insanity defense, would start next week if the jury finds Ormsby guilty of the murders.
