At least six people have been injured at a shooting in an office complex in Phoenix on Wednesday.

It's unclear if the suspect has been apprehended and authorities say this was not a random incident. It's not believed anyone died, although one person is in extremely critical condition. There are reports that three people were shot. The nature of the injuries of the other people are not known, although one is reportedly stress-related.

A SWAT team converged on a home a few miles from the scene and authorities were believed to be speaking to a person who is not considered to be the suspect.

The gunman went to the building around 10:30 a.m. and exchanged some heated words with someone else before drawing a gun and shooting three people.

The shooting came up during the congressional hearings on gun control. Mark Kelly, who is married to former Arizona Rep. Gabrielle Giffords – a victim of gun violence herself – said there was “what seems to be a shooting with multiple victims with multiple shots fired."
