INDIANAPOLIS (AP): Court records show an Indiana man who police say killed his niece, her 4-year-old son and then himself following a dispute over a family trust worth millions worked alongside his brother nearly a decade ago to distribute their father’s estate.

Hamilton County court records show Lucius Oliver Hamilton III and his older brother, Russell W. Hamilton, were appointed co-representatives of their father’s estate in June 2007, two months after Lucius O. Hamilton II’s death.

A court document filed in December 2007 indicated the brothers had finished distributing the estate’s assets “to the persons entitled” and no claims remained against that estate.

Russell W. Hamilton died in 2012. Police say Lucius Oliver Hamilton III killed his late brother’s daughter Katherine Giehll, her son Raymond Peter Giehll IV and then himself Wednesday following a family trust dispute.
