JACKSONVILLE, Fla. -- The search for a 3-year-old Jacksonville boy ended in tragedy Sunday evening.

The body of 3-year-old Amari Harley was found about two hours after the Florida Department of Law Enforcement issued a missing child alert.

The alert, which went out at around 7 p.m., was canceled and the Jacksonville Sheriff's Office broke the disheartening news around 8:45 p.m.

According to police, his body was discovered in an underground water tank after he had been playing at a park during a gathering.

His family noticed he was missing around 3 p.m. and his body was found in the underground tank around 7:30 p.m.

Authorities will perform an autopsy Monday to determine the actual cause of his death. At this point, it's too early to tell if this was an accident or if foul play was involved.
