Crews said two potentially dangerous rockets and a grenade were found about 1,000 feet behind Odyssey Middle School in Orange County.

The ammo was found by contractors for the U.S. Army Corps of Engineers less than a week after a live fuse attached to a bomb was found in the same area, near the Warwick subdivision.

"It is scary because I have three kids and I live in the Warwick community," resident Arislyda Bonetti said. "We don’t know if we find something and the kids are playing in the backyard."

Recently, parents expressed concern after the Army Corps of Engineers announced they were searching an area near the school and a neighborhood for live munitions.

"I am very concerned with these neighborhoods," Army Corps of Engineers representative Charles Fales said in an earlier report. "But I'm not calling this an emergency."

A chain-linked fence was erected between the school campus and the former bombing range as a precaution.

The U.S. Army stopped using the land near Odyssey Middle School as a bombing range in 1946. The year after that, three boys playing near the site were crippled by a live explosive but the land was not declared a potential danger by the Army Crops of Engineers until last year.
