The latest on a killing at a home in a suburban Indianapolis neighborhood that left a woman and her young son dead (all times local):

3:30 p.m.

A friend of an Indiana man who police say killed his niece, her 4-year-old son and himself says those who knew him are "dumbfounded" by the shootings.

Tom Santelli says he befriended Lucius Oliver Hamilton III in 2001 after moving to Zionsville and joined a fox-hunting group Hamilton's late father co-founded.

Santelli says Hamilton was quiet and somewhat introverted but friendly. He says those who knew the 61-year-old don't understand what could have led him to kill.

The niece and boy's bodies were found Wednesday at their home near Zionsville. Hamilton was found dead later in the day in an Indianapolis hotel room.

Police say the killings apparently followed a dispute over a family trust worth millions.

But Santelli says Hamilton was well-to-do and never mentioned any family friction over money.


12:30 p.m.

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, her son and then himself Wednesday following a family trust dispute.


1:45 a.m.

Investigators are working to determine the details of a dispute over a family trust worth millions that they believe led an Indiana man to kill his niece, her 4-year-old son and then himself.

Indiana State Police say 61-year-old Lucius Oliver Hamilton III fatally shot himself inside an Indianapolis hotel room just after officers knocked on the door Wednesday.

Hamilton had been the subject of a manhunt since shortly after the bodies of Katherine Giehll and Raymond Peter Giehll IV were found Wednesday morning in their home in an upscale neighborhood near Zionsville, just northwest of Indianapolis.

Boone County Sheriff Mike Nielsen says investigators believe the dispute led to the attack. He called it "a lingering issue that has been going on for the last few years."
