Nyeem M. Irby, 36, was found shot and killed on the night of September 1, 2017, in Phoenix near Dunlap Avenue and 35th Avenue, along a canal bank behind the water treatment facility at 3030 West Dunlap Avenue. Patrol officers discovered him lying on the ground at about 11:15–11:18 p.m.; emergency personnel pronounced him dead at the scene and his death was classified as a homicide.

The location — a secluded stretch behind the treatment plant — created a defined but challenging crime scene that officers processed through the night. Despite early work by patrol and homicide detectives, no suspect has been publicly identified; Silent Witness lists the suspect as unknown and local reports at the time said police released no suspect information. The case remains on public unsolved-homicide listings, with a reward of up to $1,000 offered for information leading to an arrest or indictment.

Does anyone with knowledge of that area or of Nyeem Irby’s movements that night have information that could help investigators?
