Much of the skepticism regarding the verdict seems to be rooted in the fact that Carter was not physically present at the time of Roy's death.
While the family will have to wait until August 3 for the sentencing of Carter, who faces up to 20 years in prison, they hope she will receive the maximum punishment.
Roy committed suicide by running a generator in his truck as he sat in a parking lot in Fairhaven, Massachusetts, about 60 miles (96 km) south of Boston.
Michelle Carter, at her trial earlier this week, had exchanged text messages about suicide with a friend who eventually killed himself. When he became sick because of the fumes, he stepped out of the truck, at which point Carter reportedly ordered him to "get back in".
He said Carter had a duty to call someone for help when she knew Roy was attempting suicide.
"She admits in subsequent texts that she did nothing, she did not call the police or Mr. Roy's family", said Judge Lawrence Moniz. The judge agreed with prosecutors that Carter's "wanton and reckless conduct" had resulted in the death of Conrad Roy III.
"This has been a very tough time for our family and we'd like to process this verdict that we're happy with", he said.

"Miss Carter had reason to know that Mr. Roy had followed her instruction and placed himself in the toxic environment of that truck, " Moniz said. "The time is right and you're ready, you just need to do it!" to him, and at one point, when the teen got scared and exited his vehicle, Carter told him to "get back in" the auto.More news: Rumor Central: Could big offer lure Andre Iguodala from Golden State?

What do you think of the verdict?
"You already made this decision, and if you don't do it tonight you're gonna be thinking about it all the time and stuff all the rest of your life and be miserable".
Carter's defense team tried to argue that Roy was suicidal for years before committing the act, and likely would have taken his own life regardless of Carter's help. " ... I'm sorry I wasn't the boy you wanted".
Carter waived her right to a jury trial. She was exhausted of his "excuses", she said several times.
"It's sad, it's tragic", Cataldo said.
Assistant district attorney Katie Rayburn tells reporters that both defendant Michelle Carter's family and the family of her boyfriend, Conrad Roy III, "have been torn apart".
According to CNN, Carter's guilty conviction could set a legal precedent in MA on whether or not it is a crime to tell someone to commit suicide. "I just want to make sure tonight is the real thing".
