Backed by the United States gov ernment, two Indian children have filed claim against the estate of Curt Cronemeyer, who was killed recently in his store in Alletown, Ariz. It is claimed the little boy and little girl are Cronemeyer's offspring. It has been supposed that Cronemeyer's only heirs were three sisters living in Ger many. The United States attorney general's office has issued orders to protect the interest of the little al leged half-breeds. The older of the children is 12 years. Cronemeyer’s estate is said to be worth in the neighborhood of $65,000.
