Miriam Carey (CBS 2, New York)
(USA Today) -- The family of the woman who was shot and killed after leading police on a car chase through D.C. streets is questioning whether she needed to die.
Miriam Carey, a 34-year-old dental hygienist, led officers on a high-speed chase from the White House to Capitol Hill on Thursday after first crashing her car into a barrier at the White House. She was shot and killed fleeing her car near a Senate building.
"We are still trying to put the pieces together," her sister, Amy Carey-Jones, told CNN Friday.
"Our real concern is why?" she said. "Were things done properly? Was there some other way she could have been helped so that it didn't end tragically?"
Carey's other sister, Valarie, told CNN's Anderson Cooper that "regardless of the reason that she was there (in Washington D.C.), her life shouldn't have ended there."
Valarie Carey said the family came to Washington, D.C., to find out what happened. When asked whether she felt law enforcement had reacted properly in the incident, she said, "That's something that has to be looked into further. This is the reason the family is here. We're here for answers."
Carey was not armed. Two federal officials, who were not authorized to comment publicly, told USA TODAY that all shots were fired by law enforcement officers and that no gun was recovered from her car.
Carey's 1-year-old daughter was in the car with her but was not injured in the incident. She is now in protective custody.
Law enforcement officials said Friday that Carey was delusional and believed that President Obama was communicating with her. The officials, who have been briefed on the investigation, spoke to USA TODAY on condition of anonymity because they were not authorized to speak publicly about the ongoing investigation.
