The siblings were apparently trapped underneath the rubble for several minutes until emergency officials arrived to free them. They were rushed to a nearby hospital, where they died several hours later, FOX8 reported.
There was no indication of whether the parents were home at the time of the accident.
Scout was in ninth grade and Chasey was in seventh grade, said a spokesperson for Hathaway Brown School, where the girls attended.
The U.S. Sun reported that Chasey was known for her artistic abilities and a keen sense of humor, while Scout was an athlete and devoted older sister.
"You couldn't be around them without smiling or laughing," said Sharon Baker, the school's director of Middle School, Fox 8 reported. "They brought such joy into every room they entered."
“The entire HB community is saddened by the loss of the Scaravilli sisters; they will be greatly missed by so many friends, classmates, and teachers,” Hathaway Brown Head of School Fran Bisselle said in a statement, according to Fox8. “Our thoughts and prayers are dedicated to their family.”
A vigil was held Monday at the school.
The school planned to keep grief counselors staffed for students and parents.
The girls are survived by their parents and two younger sisters.
Their father said the entire family is “hurting.”
In an interview with WKYC, he said: "They were beautiful people. They were beautiful souls. I'm gonna miss them terribly."
The accident remains under investigation.
