The Latest on a double killing at a home in upscale suburban Indianapolis neighborhood (all times local):

4:15 p.m.

Police say a man wanted in connection with the fatal shootings of his niece and her young son in suburban Indianapolis has killed himself at an Indianapolis hotel.

Indiana State Police Capt. Dave Bursten says 61-year-old Lucius Oliver Hamilton III was found dead of self-inflicted gunshot wounds at a hotel one block from the Indiana Statehouse on Wednesday afternoon.

Hamilton had been the object of a manhunt since shortly after the bodies of 31-year-old Katherine Giehll and her son, 4-year-old Raymond Peter Giehll IV, were found in their home in Zionsville, just northwest of Indianapolis. Boone County Sheriff Mike Nielsen says the bodies were found Wednesday morning.

Nielsen hasn't revealed a motive for the slayings.

Hamilton was employed at Wabash College in Crawfordsville, which authorities locked down and searched while Hamilton was at large.

A sheriff has identified the woman and child found shot to death in their home in an upscale suburban Indianapolis neighborhood.

Boone County Sheriff Mike Nielsen says 31-year-old Katherine Giehll was found shot to death just inside the home in Zionsville and her son, 4-year-old Raymond Peter Giehll IV, was found in a living room where he had been watching television.

Nielsen says he believes a neighbor found the bodies around 8 a.m. Wednesday.

He says authorities are searching for a 61-year-old uncle of the woman who's believed to be armed and dangerous. The man is employed by Wabash College in nearby Crawfordsville. The campus has been placed on lockdown and is being searched. Classes have been canceled there for the rest of the day.
