Carter was 17 when the 18-year-old Roy was found dead of carbon monoxide poisoning in 2014.

Carter's lawyer argued that Roy was determined to kill himself and nothing Carter did could change that.

Roy's aunt has asked the judge to sentence Carter to the 20-year maximum. Carter's father said his daughter made "a tragic mistake." He's asking for probation and continued counseling.
