On Wednesday, Mosley and Myers were taken into custody at Mosley’s home in Clayton, Montgomery County, and Back’s body was recovered from rural Preble County.
Back was expected to join the U.S. Navy in February. He attended the career center in Clearcreek Twp. and high school in Waynesville before graduating in 2013.
On Thursday, an orange sign, “R.I.P. Justin,” near the entrance to Waynesville High, was marked with goodbyes to Back.
“You were too young, I miss you already. We won’t forget you. Fly high,” wrote Lexie Adams.
In Waynesville, Back, a music lover, played football, helped construct sets for Waynesville High School drama productions and was recognized for his perfect attendance.
“I will never forget how you stood up for me. Thank you for being such a wonderful person,” Chris Poole wrote.
At the career center, Back completed the Fire Science program. Instructor Tim Keene described Back as quiet, polite and respectful.
“Cadet Back worked hard and always did everything I asked him to do,” Keene said in a release. “He came in recently with his Navy recruiter to introduce him to me, and he was excited about going into the Navy.”
Both schools made preparations and provided counselors to help students and staff deal with Back’s death.
Authorities said Back and Myers apparently knew each other when Myers attended school in Waynesville, before leaving for Northmont in 2009. Contrary to reports Wednesday, Mosley was not a student in Waynesville. Neither Mosley or Myers attended the career center, officials said.
A grand jury is likely to issue indictments over the weekend, binding the case over to Warren County Common Pleas Court.
