Man Pleads Guilty in Horrific Niagara Falls Domestic Violence Case, Killing Mother of Four

A Buffalo man is facing a lengthy prison term after pleading guilty Monday, April 14th, to charges tied to a domestic violence homicide that shocked Niagara Falls residents earlier this year.

Keith William Hill, 32, admitted to multiple felony counts stemming from the March 31st killing of Tania Wilson, a mother of four. His guilty plea covered charges including second-degree murder, aggravated criminal contempt, and second-degree criminal contempt.

Initially pleading not guilty and held without bail, Hill now faces a maximum sentence of 23 years to life in prison. Niagara County Court Judge Caroline Wojtaszek informed him of the sentencing cap during the court proceedings.

Niagara Falls police responded to a late-night call around 11pm on March 31st at a residence on Orleans Avenue following reports of a domestic disturbance. Upon arrival, officers discovered Wilson’s lifeless body inside the home. The 39-year-old woman had sustained multiple stab wounds and was pronounced dead at the scene.

Also inside the home were her four children, whose ages range from toddlers to teens. They were unharmed physically and are now in the care of relatives.

Further investigation revealed a troubling history of domestic violence between Hill and Wilson, including a previous weapons possession conviction for Hill. Detectives uncovered a prior incident and an active arrest warrant for Hill related to a February 2024 violation of a protection order issued in Pennsylvania. This was an order specifically prohibiting contact with Wilson.

Authorities arrested Hill on April 4th and the Pennsylvania contempt charge remains pending. The ongoing investigation also linked him to a 2021 weapons case in Buffalo.

The case now moves to sentencing.
