Gray would allegedly go on to fatally shoot two classmates and two teachers at Apalachee High School in Winder, Georgia, Wednesday.
The children were between 13 and 18 years old, and were recovered in Cleveland and Akron, Ohio. One victim was found in Washington state.
In May 2023, authorities interviewed the 13-year-old suspect about the rumored threats to commit a school shooting.
Arielle was last seen leaving her Fort Myers, Florida, residence last Wednesday. Police in Florida are clearing up "misinformation" that a pair of shorts found in the vicinity of the body of a dead jogger belonged to the victim.
