A caller reported a possible homicide to police at 10:57 p.m. after a suspect told the caller that he had killed a man in a mobile home. Police found the victim's body inside the mobile home in the 2400 block of 24th Avenue a short time later.
While the man's cause of death has not yet been released, police said he was a victim of homicide.
The suspect who told the caller he was responsible remains at large, but police said that his identity is known.
Earlier in the evening, police responded to two shooting deaths. The first occurred in the 1000 block of 102nd Avenue at 6:25 p.m., according to police spokeswoman Officer Johnna Watson.

Police discovered a young man lying in the street suffering from a fatal gunshot wound. Medical personnel pronounced the victim dead at the scene, police said.
