WASHINGTON (AP) — A federal law enforcement official says the woman killed by police after trying to drive through barricades outside the White House had believed the president was communicating with her and was delusional.
The official, who had been briefed about the investigation, spoke on condition of anonymity Friday because the person was not authorized to speak publicly about the ongoing investigation. The official says the woman, 34-year-old Miriam Carey, had been in a deteriorating mental state since December.
The official says investigators have been interviewing the woman's family about her mental condition. The official says investigators believe the woman drove directly to Washington immediately before Thursday's car chase in the nation's capital that prompted the shooting.
