The incident began just before 11 a.m. PT on Tuesday when officers received a report from "ShotSpotter" that shots were being fired in downtown Fresno. Soon after, shots were fired at 3 additional scenes in the area.
According to Police Chief Jerry Dyer, the gunman first opened fire at a pickup truck, striking someone inside the vehicle. Another person drove the pickup truck to the Fresno Police Department, but the victim succumbed to his injuries.
Seconds after the first shooting, the suspect fired multiple shots at a pedestrian in the area but missed. He then shot and killed two other people, including someone who was near a bus stop outside the parking lot of Catholic Charities.
A short time later, a police officer spotted the suspect, who "literally dove onto the ground" as soon as he spotted the officer. While being taken into custody, the man - identified as 39-year-old Kori Ali Muhammad - shouted "Allahu Akbar."
It was not immediately clear whether Tuesday's shooting spree was an act of terrorism, but Chief Dyer said Muhammad's Facebook account indicated that he "does not like white people." He also expressed anti-government sentiments.
Muhammad was already wanted in connection with the murder of a security guard at a motel in Fresno.
