Authorities have begun an investigation into Thursday's incident on Washington D.C.'s Capitol Hill where the suspect, Miriam Carey, rammed her car into a security barrier near the White House before leading the police on a high-speed car chase that ended with her being shot dead, Fox News reported.

According to Michael McCaul (R-Texas), chairman of the House Homeland Security Committee, the woman originally tried to run down a Secret Service agent who was stationed near the White House, and the Secret Service added in a statement, cited by Fox News, that multiple gunshots were later fired at two locations near the Capitol.

The incident appears to have “no nexus to terrorism" and police officials, who believe Thursday’s was an isolated incident, told the media that the suspect was killed after being struck by police gunfire. Two officers were injured in the incident and both of them were immediately admitted to a hospital.

Metropolitan Police Chief Cathy Lanier said the officers acted "heroically," and added that the two officers who were injured -- one from the U.S. Capitol Police, or USCP, and the other from the Secret Service -- "will be okay."

According to Fox News, the USCP officer, who was injured in a related car crash, was released from the MedStar Washington Hospital Center on Thursday night.

The FBI has issued a search warrant in connection with the investigation, to inspect the suspect’s home in Stanford, Conn., in hopes of finding a motive behind the attack. Police officials have also cordoned off a condominium building in Stamford, Conn., and the surrounding neighborhood.

Carey, a 34-year-old dental hygienist, grew up in the Bedford-Stuyvesant section of Brooklyn, and her family and friends in the area are said to be in shock following the incident.

“It’s like anyone else — how would you feel?” Eric Sanders, Carey’s family attorney was quoted as saying by CBS New York. “You see these things happen to people, and you wonder how did this happen. It’s out of the ordinary. So of course they’re shocked.”
