Three people were killed and two were injured Friday in four shootings in north Tulsa, Oklahoma and police are searching for a lone suspected gunman, they said.

Tulsa police spokesman Capt. Jonathan Brooks said investigators were looking into whether the shootings may have been possible hate crimes.

"We're not absolutely certain, but a hate crime is a possibility. And we'll go with where the investigation leads us," he said.

All of the victims are black. The suspected shooter is a white male and is believed to be traveling in a white truck, said Brooks.
