Washington (CNN) -- Authorities investigating why a Connecticut woman rammed barricades and led police on a chase near the U.S. Capitol found medications in her apartment to treat schizophrenia and other mental disorders, a law enforcement source briefed on the investigation said Friday.
The woman was identified by law enforcement sources as Miriam Carey, 34. She was shot dead Thursday in the incident, which played out in one of the most heavily policed places in the world, temporarily locked down Congress and sparked anxiety among tourists and staffers alike.
Two law enforcement officers were injured. Police say Carey rammed barricades and police cruisers and sped down Pennsylvania Avenue before crashing.
She apparently did not have a weapon, but did have a 1-year-old child in the car with her. The child emerged from the chaos unharmed, officials said.
Authorities who searched the apartment in Stamford, Connecticut, found one medication to treat schizophrenia and bipolar disorder, and another that is an antidepressant, according to the source.
A law enforcement source involved in the investigation said Thursday that the woman's boyfriend had told police last winter that she appeared to be delusional.

Carey's boyfriend contacted police in December saying he feared for the safety of their child, who was 4 months old at the time, according to a law enforcement source involved in the investigation. The boyfriend said the woman was acting delusional, claiming the president had placed Stamford under lockdown and that her house was under electronic surveillance, the source said.
He told police that she was suffering from post-partum depression, was having trouble sleeping and was on medication. Carey underwent a mental health evaluation, said the source, who added that the boyfriend has been questioned by federal authorities about Thursday's events.
The source told CNN that Carey left a letter addressed to the boyfriend at her apartment and that it appeared to contain white powder. The letter was being tested for hazardous substances.
