[Fay and Loretta O’Connell were married in 1940 and owned their residence along with
several bank accounts as joint tenants, with rights of survivorship. They had no children.
Loretta had a sister, Mary Ann Raher, and two brothers, Milo Kettler and Robert Kettler. On
November 21, 2005, the couple executed wills, both directing the residue of their estates
pass to the survivor. On the second death, after certain specific bequests, the residual estate
would pass to Milo and Robert. Loretta’s sister was not included as a beneficiary in the
residual estate of either Fay or Loretta, but was to receive $10,000 under Loretta’s will. On

for the care of Loretta, if she survived him. If Loretta did not survive him or upon Loretta’s
death, after certain bequests, the balance of the trust assets was left to Mary Ann. Milo and
Fay died on August 9, 2007. In October 2007, Loretta, Milo, and Robert filed a petition
naming the personal representative of Fay’s estate, Security National Bank (SNB), and Mary
Ann as defendants alleging conversion of Loretta’s property by Fay and Mary Ann. In
February 2009, the district court issued a summary judgment ruling. The district court found
