PHOENIX - Police say a gunman who shot three people at a Phoenix office building got into a dispute with someone at the building.
Sgt. Tommy Thompson says the dispute escalated to the point where the man pulled out a gun and shot three people.
Thompson did not know what kind of gun was used.
One of the victims was in extremely critical condition when taken from the office complex. Two others who were shot had less severe injuries.
Thompson says police do not know the whereabouts of the shooter.
Fire Capt. Scott McDonald says all those shot had life-threatening wounds. He said two other people had minor injuries that he would not describe in detail.
Reports from the scene suggest there may be at least two additional people who have been wounded, which would bring the total to five.
Around 10:30 a.m., officials reported that three people had suffered gunshot wounds in a building on the 7300 block of 16th Avenue, officials said. It is unknown if the shooter is in custody.
Aerial pictures from the scene show dozens of officers canvasing the scene and entering the building to search.
Witnesses say the suspect escaped the scene in a white vehicle, but that has not been confirmed.
According to Larry Ruch, who operates out of a law office across the street, there are 50 police cars, seven to eight fire trucks, K-9 units at the location. It appeared to him that four people were taken out on stretchers.
The Chevron gas station at the northwest corner of the intersection has been cordoned off, and traffic is reported to be heavily congested.
