U.S. Capitol Police Chief Kim Dines believes Carey had a female child in the vehicle. She was not injured.
A police officer was reportedly injured. Police said they have no reports of an officer being shot. It is believed the Carey's car struck a police car with the officer inside.
ABC News also reported that at least three other people were also injured. It is unknown if the injuries were caused by gunfire.
Police were seen on a local news feed surrounding a parked car. An unknown person was also seen being loaded into an ambulance.
Police have ruled out terrorism as a possible motive and said it was an isolated incident.
Arizona Rep. David Schweikert said the shooting took place on the Senate side of the Capitol. He was about 100 yards outside the Capitol when he was alerted that the building was going on lockdown.
The reported area of the shooting, First Street and Constitution, has parking for Senate members and a few "small monuments," according to Schweikert.
Tweets saying police were scrambling after possible gunfire began to be sent out about 11:25 a.m. Arizona time.
