Story highlights Police responded Saturday morning to a call about shots fired

They arrived to find five people and two dogs dead of gunshots

One of the dead was the suspected gunman, police say

Police in Phoenix, Arizona, found a horrific scene Saturday morning at a condominium complex, where five people and two dogs were dead of gunshot wounds, a police spokesman said. The dead included the apparent shooter.

Officers responded to the complex in the center of town after a resident reported someone firing shots at his home, Sgt. Tommy Thompson of the Phoenix Police Department said.

When police arrived, the caller told them the gunman fled on foot. Another person came up and reported shots being fired elsewhere in the complex, Thompson said.

Police narrowed their search to two apartments. In the first one, they found two people dead on the patio and two others dead inside, along with the two dogs, Thompson said.

The officers went to the apartment next door and found the suspect dead of a self-inflicted gunshot wound.

Police released no names; Thompson said investigators are still seeking a motive.

Resident Libni DeLeon told CNN affiliate KNXV that he heard a knock on his door in the morning before the man started shooting through his front door. DeLeon said one of the bullets went through his bathroom and into his kitchen.

"When I ran upstairs, I kind of got a glance at him," DeLeon told the station. "When I glanced at him I yelled at him, and then he turned around and shot two more rounds upstairs."
