Three people at a Phoenix, Ariz., office complex were shot Wednesday morning, and the shooter's whereabouts are unknown, local police say.
Officer James Holmes said the victims were taken to hospitals. He did not know if their injuries were life-threatening.
Holmes said police believe there was only one shooter, but they don't know his whereabouts.
"We have no motive," Holmes said. "It is right now a really fluid scene."
He said police were given conflicting information about the suspect leaving the scene. The building was evacuated and police are looking for a suspect or any additional victims.
Vannessa Brogan, who works in sales support in an insurance business in the three-storey complex, said she heard a loud bang that she thought at first was from somebody working in or near the building.
She said others at the business thought they heard multiple loud noises. She said people locked themselves in offices until authorities evacuated the central Phoenix building that houses insurance, medical and law offices.
Becky Neher, who works for a title company in the building said the two gunshots she heard sounded like two pieces of metal banging against each other.
"We were doing our regular morning routine, and I hear what I guess were two gunshots," she said.
Watching from her second-storey office, she saw people below leaving the building.
"Someone yelled, 'We have a shooter,'" she said. She saw two victims lying on the ground outside the back of the building. She said there are medical people who have offices in the complex, so they came out to help.
