New Jersey authorities recently detonated two World War II explosives discovered in a neighborhood, only to find a third later in the same yard.

Kyle M. Anderson had landscapers dig up the backyard of his newly-purchased property in Cape May, expecting to find strange things after a neighbor told him the previous owner had buried a lot of items.

"The yard is lumpy and uneven," Anderson told ABC 6 News this week. "When the landscapers came, I advised them there will be things buried back there."

Anderson is the father of Kyle Anderson, a basketball player for the Memphis Grizzlies.

Once removed, the explosives were taken to a beach and detonated in a "safe and consistent" manner, the Cape May Police Department (CMPD) posted on Facebook.

The bomb squad returned Thursday with metal detectors to see if any other dangerous objects remained buried, finding a third explosive.
