NAMPA -- Police are scaling back a search for a man sought after a report of gunshots in a Nampa neighborhood Tuesday morning.

Canyon County spokesman Joe Decker said the "shots fired" call came in at about 11:15 a.m. at an address on McDermott Road near Lake Hazel Road. Multiple people left the scene, both in cars and on foot, Decker said.

Two people were quickly detained for questioning, and police launched into an extensive search for a third man, who authorities said may be armed. That man's identity and description have not been released.

Deputies, with help from Ada County law enforcement, combed the area and searched the fields around McDermott Road using a drone and police dogs, but were unable to find the suspect.

Decker said shortly after 2:40 p.m. that Canyon County would begin "downsizing" the search, although deputies remain at the scene talking to witnesses.

It's unclear whether anyone was actually struck by the gunfire. Decker said the sheriff's office had "reports of possible evidence indicating someone may have been injured," but have not located anyone who is hurt.

A house in the area was blocked off with crime scene tape, and law enforcement towed a yellow car from the scene.

Anyone who notices suspicious activity or has any information about the case is asked to contact law enforcement.
