This is poorly written, but making some assumptions it sounds as if they went over their caller id logs and retrieved the number that had called at 3:17pm when the bomb threat call was actually another hour further down the list.
Heads should roll. You don’t jail someone for 2 weeks before checking the evidence.
ok, that part is now clear, but why would the kid be callin the school that early in the mornin anyway?
if this article were any more vague I’d swear it was written by my ex-wife who was ALWAYS vague when she was mad at me..
