Wayne County Sheriff's Office Capt. Tom Effler said that Dahamoney Hakem Murchison, 18, first reported that several people pulled up in a vehicle and fired a BB gun at a group of students.
Murchison had a BB gun wound in his arm, but he later admitted that he made up the story of how he was injured, Effler said.
Investigators determined that Murchison was among a group of students playing with a BB gun at the high school and that he was shot while playing with the BB gun.
Christopher Michael Hines, 17, and Calvin Darnell, 16, were charged with possession of a weapon on educational property. Murchison was charged with filing a false report to police.
"The student that originally filed the report cooperated with the investigation and admitted his mistake, but I must emphasize that a false report still expends many manhours and can cause concern and alarm to other citizens, especially when it occurs at a school," Sheriff Carey A. Winders said in a statement.
