Rep. Mike McCaul: DC Suspect Had No Weapons in Car

Law-enforcement officials declined to say whether the woman shot and killed by police in Washington, D.C., Thursday had weapons, but a member of Congress says he was told that she did not.

"From what I understand, she didn't have any weapons in the car," Rep. Mike McCaul, R-Texas, told CNN on Thursday.

McCaul, chairman of the House Homeland Security Committee, described the person who rammed a barricade near the White House before leading police on a chase several blocks to the Capitol as a 34-year-old woman from Connecticut.

None of the information McCaul gave to CNN has been confirmed by Washington's Metropolitan Police Department, which is heading the investigation.

Police shot the woman to death after her car crashed near the Capitol. She reportedly refused to follow police orders.

The woman may have had mental health issues, McCaul said he has been told by multiple sources. The woman's 18-month-old daughter was in the car, but was unharmed in the incident.

McCaul said he was told by Homeland Security and the FBI that the incident is likely isolated and not connected to terrorism.

"It hasn't been ruled out completely," McCaul told CNN, and the FBI is digging into the woman's background.

A reporter at an earlier press conference with police officials asked whether the woman, who was black, was of Somali descent. Police would not answer that question, or any others about the suspect, and McCaul said he is unaware whether the woman is American or an immigrant. He also said he has not been told her name.
