A college fundraiser, wanted for the "heinous" killings of his niece and her 4-year-old son, shot himself to death after barricading himself in a hotel room following a day-long manhunt, authorities said.
Lucius Oliver Hamilton III, 61, was found dead in a fourth-floor room at a Hilton Hotel in downtown Indianapolis, officials said. He died from a self-inflicted gunshot wound to the head, police said.
Hamilton, a noted fundraiser for Wabash College, had been sought by Boone County Sheriff's deputies since Wednesday morning, when the bodies of Katherine Janet Giehll, 31 and Raymond Peter Giehll IV, 4, were found shot to death in their upscale estate.
Sheriff Michael Nielsen called the killings "heinous and heartbreaking." The boy's body was found in the living room, where he had been watching television.
His mother's body was found near the home's front door.
Wabash College, one of the few remaining all-male liberal arts institutions, was briefly put on lockdown as officers searched the campus for Hamilton. He was not there, authorities said.
On Wednesday evening, after Hamilton's body was discovered at the hotel, the Sheriff's deparment said in a statement that his motives in the killings were "strictly for financial gain," the Indianapolis Star reported.
A family trust was at issue, the statement said, and involved millions of dollars. Details of the trust are being investigated.
Police said they tracked Hamilton's car to the downtown hotel, where shots were fired. Police said officers did not fire their weapons, and portions of the fourth floor were evacuated.
Hamilton's body was found inside room 401, according to local reports.
