A man shot and killed three people in downtown Fresno, CA, on Tuesday before surrendering to authorities, the Fresno Police Department said.

The suspect was identified as Kori Ali Muhammad, a 39-year-old man who was wanted in connection with the shooting death of a security guard outside a motel Thursday, said Police Chief Jerry Dyer. The FBI has been notified of the shooting deaths, reports the Los Angeles Times.

In less than a minute, Dyer said, 16 shots were fired at four different locations. Gunfire erupted at 10:45 a.m. in the 300 block of North Van Ness Avenue. A few seconds later, a second shooting was reported. A third shooting was reported, then a fourth.

An officer in the area spotted the gunman running south on Fulton. The gunman then "dove onto the ground" and was taken into custody, the chief said.

"As he was taken into custody, he yelled out 'Allahu Akbar,'" Dyer said. He said Muhammad had expressed hatred toward white people and the government. Dyer said he wasn't clear if the shootings were terrorist-related.
