ZIONSVILLE, Ind. (Feb. 17, 2016) –The man suspected of killing his niece and her 4-year-old son in their Zionsville house was found dead in a downtown Indianapolis hotel room following a manhunt that began Wednesday morning.

Officers were called to a home in the 6800 block of Old Hunt Club Road around 8:50 a.m. in rural Zionsville. Investigators say a neighbor called police after finding the bodies of 31-year-old Katherine Janet Giehll and 4-year-old Raymond Peter Giehll.  Authorities say Giehll and her son died from gunshot wounds.

Authorities soon launched a manhunt for Giehll’s uncle, 61-year-old Lucius Oliver Hamilton III, a Wabash College employee, who checked out a 2013 Dodge full-size van at 9:30 a.m. from the college.

The all-male college was placed on lockdown as authorities searched every building for Hamilton.

“I will not stop until I find you. We have a great team assembled here, and we will find you,” Boone County Sheriff Mike Nielsen said at a press conference. “And we will find you today. I suggest if you see this or if you hear this that you turn yourself in immediately.”

Nielsen said the Boone County Sheriff’s Office was collaborating with police in Zionsville, Whitestown and Lebanon as well as Indiana State Police to solve the case. Federal agencies have also been called to assist, Nielsen said, including the U.S. Marshals Service and FBI.

Around 3:30 p.m., Sheriff Nielsen said they tracked Hamilton to the Hilton Indianapolis Hotel and Suites in the 120 block of West Market Street downtown, and about 20 minutes later, he announced that Hamilton shot and killed himself inside a hotel room.

Investigators believe the motive behind the killings was financial gain from a family trust.

According to Indiana State Police, law enforcement officers knocked on the door, and Hamilton responded, “Yes.” Upon realizing it was law enforcement at the door, two shots were fired. Contrary to what authorities previously reported, no shots were fired at officers.

Officers determined with electronic equipment that Hamilton was in the room but not moving, so at that time they entered the hotel room with the assistance of hotel employees. Authorities say Hamilton died from a single gunshot wound to the head, using a semi-automatic pistol. Officers found alcohol and prescription drugs inside the hotel room.

The vehicle Hamilton was last seen in was located and will be processed as part of the crime scene; the location of the vehicle is not being released.

“I could not be more proud of all the law enforcement officers involved today. Agencies from across the state, including our federal partners, offered every resource available to locate Hamilton. We were able to utilize these resources to work, process and secure the scene. Through many investigative techniques, we were able track Hamilton down to a specific location in downtown Indianapolis where he cowardly took his life instead of choosing to face justice for his actions. My heart goes out to the Giehll family and to the first responders that witnessed this horrific scene,” said Sheriff Nielsen.

Hamilton is listed on Wabash College’s website as a senior major gifts officer and was last seen on campus Wednesday morning. As a result of the investigation, classes at Wabash College were canceled for the first time since President John F. Kennedy’s assassination in 1963.

Investigators believe the motive for the killings was for financial gain from a family trust.

Ron Evans, head of school at Traders Point Christian Academy, where 4-year-old Raymond attended, sent this letter to families:

Dear Traders Point Christian Schools family,
