A 17-year-old West Tennessee girl who survived a suspected drug overdose has been charged with murder in the death of two classmates who did not.

The three girls, all juniors at Fayette-Ware High School, were found in the school’s parking lot on Tuesday, just hours before the school’s graduation, the Commercial-Appeal said. The girl who has been charged what taken to a hospital in critical condition, but she has since recovered.

One of the victims was identified by her father as 16-year-old Alyssa Thorne, WATN reported. The other victim, who has not been named, was 17.

The suspect, who has also not been named, appeared in juvenile court on Thursday where a judge described the incident as a “horrible, sad, sad, situation,” WREG reported.

Investigators told the court that fentanyl was found at the school and at a home. They also said that text messages and social media helped them find evidence to bring charges.

The judge released the girl into the custody of her grandmother, telling her, “I still believe in you.”

“You are lucky to be here today,” the judge said. “This is something you will never forget.”

The girl was ordered into house arrest and must undergo drug screenings and routine counseling.

According to WMC, a hearing is scheduled for June 7 to determine if the girl will be tried as an adult. She has been charged with second degree murder.
