Sofyan Boalag, 37, has been found guilty of sexually assaulting two women, and a girl in St. John's in the late summer and fall of 2012.
Outside of court following the verdict, the girl, who was 15 when Boalag raped her said, "I'm completely relieved, and I think justice has been served."
During the trial, she testified behind a screen so she wouldn't have to see Boalag. She said that testifying was difficult for her. "Traumatic to say the least. But I'm glad I went through with it."
Judge Pamela Goulding handed down her decision in a St. John's courtroom Tuesday morning, saying in her written decision "I am satisfied the prosecution has proven its case beyond a reasonable doubt" for 13 of the charges.
All three of the sexual assault convictions involved a weapon. The other guilty charges included possession of a dangerous weapon, theft and resisting police.
The other charges against Boalag involving three other women were dismissed.
For the 15 year old, who is now about to start university, Boalag's attack was her first sexual experience, but she says she has dealt with it.
"It's been extremely hard," she said outside court after the verdict. But it gave me the strength to come out as who I really am. It's given me a lot of strength and resilience."
But she said the attack has still left her fearful at times.
"I still look over my shoulder, and if there is somebody behind me with a hood or anything like that, I still get petrified. But it's improving," she said. "It's been a hard road, and there's definitely been a lot, a lot of bumps, but I came out on top."
"I hope he stays in that jail cell until the end of his days."
In one of the incidents where the charges against Boalag were dismissed, the witness came into court but said she didn't want to testify. But as she was leaving court, said to Boalag, "Hope they cut your f...king head off. Hope you die somewhere you f...king pig."
In one of the other incidents, the woman said she struggled with Boalag, but there was no sexual assault, and he ran off.
As well as the 15 year old, another woman also testified at the trial behind a screen to avoid seeing Boalag because of fear or anxiety.
Boalag did not take the stand in his own defence. He has been in custody since his arrest in 2012.
The matter is back in court August 10 when a date may be set for sentencing.
