Carl M. Hosmer of Niagara Falls was sentenced Wednesday to 18 years in prison for his role in the 2016 killing of Daniel F. Sparks.
Hosmer, 29, had once shared an apartment with the victim. Sparks' decomposed body was found Dec. 6 in a brush-covered area behind the Cataract Steel plant on Mackenna Avenue in the Falls, after Hosmer reported the incident to police.
State Supreme Court Justice Richard C. Kloch Sr. said that was why he agreed to give Hosmer a shorter sentence than the 25 years he imposed Tuesday on James W. Howard, 28, of Lockport, whom Kloch concluded was the primary killer.
Both men pleaded guilty to first-degree manslaughter.
Sparks, 44, was stabbed 27 times in the torso and upper legs and died between Oct. 14 and 16, an autopsy determined.
