Washington ( CNN ) -- Authorities searching the home of a Connecticut woman who rammed barricades and led police on a chase near the U.S. Capitol found discharge papers from a 2012 mental health evaluation that listed prescriptions to treat schizophrenia and other mental disorders , a law enforcement source briefed on the investigation said Friday . The woman , identified by law enforcement sources as Miriam Carey , 34 , died after police shot her . Earlier , sources said investigators found medications , but that proved later not to be accurate . Carey 's boyfriend told police in December that she appeared to be delusional , believing that President Barack Obama had placed Stamford , Connecticut , where they lived , under lockdown and that her home was under electronic surveillance , a law enforcement source involved in the investigation said . Thursday 's incident 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 . Police say Carey rammed barricades and police cruisers -- actions Washington police Chief Cathy Lanier said appeared deliberate -- and sped down Pennsylvania Avenue before crashing . Two law enforcement officers were injured , and officers shot her to end the incident . The Carey family is questioning whether shooting her was the only way to end the chase . `` We want to know if protocols were followed , '' family attorney Eric Sanders said on CNN 's AC360 . Carey apparently did not have a weapon , but did have a 1-year-old girl in the car with her . The child -- Carey 's daughter -- survived the chaos unharmed , officials said . The child has been taken into protective custody by the D.C. Child and Family Services Agency . She has been temporarily placed with a foster family , according an agency spokesperson . Carey 's family has identified the woman 's body , said Beverly Fields , a spokeswoman for the Office of the Chief Medical Examiner . Why a new mom might put herself -- and her child -- in harm 's way . Authorities who searched Carey 's apartment in Stamford found discharge papers that listed risperidone , a medication to treat schizophrenia and bipolar disorder , a law enforcement source said . They also found paperwork listing escitalopram , an antidepressant commonly prescribed under the brand name Lexapro , according to the source . It was not known if she was taking any of the medications , and authorities have not officially linked the incident to mental illness or any other factor . According to Xavier Amador , a psychologist and expert in schizophrenia and other mental health disorders , it is possible the medications were prescribed for postpartum psychosis , a rare illness that usually comes on suddenly within the first four weeks after birth . A few months after her daughter was born , Miriam Carey was diagnosed with postpartum depression with psychosis , her sister , Amy Carey-Jones , said on CNN 's `` AC360 . '' `` There was n't a pattern . It was something that occurred suddenly , '' Carey-Jones said . `` She seemed overwhelmed . There was a lot of stress . `` There was not moments of her walking around with delusions . That was not what was going on . '' Her sister made progress with the help of counseling and medications . Carey-Jones said her sister recently told her that the doctors said she did n't need the medication anymore . `` They tapered her off the medications , and she said she felt fine , '' Carey-Jones said . She declined to discuss what medication her sister had taken . Carey 's boyfriend contacted police last winter , when their child was four months old , according to the law enforcement source who told CNN about the boyfriend 's reports to police . 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 . A car chase , gunshots . Thursday 's drama began around 2 p.m. , when the woman steered a black Infiniti near the White House , a U.S. Secret Service source said . She drove up to a barrier at the 15th and E street checkpoint and was approached by Secret Service officers . She hurriedly made an erratic three-point turn , striking the barrier and backing into an officer before driving away , the source told CNN . Police said the car sped down Pennsylvania Avenue toward the Capitol , where security vehicles stopped it at Garfield Circle . The woman slammed the car into reverse , crashing into a police cruiser , and tried to get away . At that point officers began firing , a witness said . Dramatic video footage by a videographer for Alhurra TV , a Middle Eastern news outlet financed by the U.S. government , showed the black vehicle then speeding around a nearby traffic circle with a police car in close pursuit and then heading away . The car crashed into more security barriers a few blocks later , witnesses said . More shots were fired after the vehicle stopped , and the woman was hit several times , said Metropolitan Police Department Chief Cathy Lanier . Carey was later pronounced dead , Lanier said . Two officers were injured . A Capitol Police officer whose vehicle crashed during the chase was hurt , authorities said . The officer was released from a hospital Thursday night . The Secret Service did not release information about its injured agent . Chaos and a child in the car . Inside the woman 's car was the 1-year-old child , who was not harmed . The child was taken into protective custody , officials said . Officers did n't know there was a child inside the woman 's car during the chase , officials said . Also , the early investigation revealed that there was no evidence that the woman had a gun or fired a shot . The bedlam from the fatal chase reverberated throughout a U.S. Capital already shaken by the recent mass shooting at the Navy Yard in the city and on edge due to tensions over the showdown over shutting down the federal government . Authorities locked down the Capitol building and other government facilities in the area . House and Senate sessions were immediately suspended , with legislators ordered to take cover and keep away from windows . Police also closed Pennsylvania Avenue in front of the White House . Sirens blared as people in and around government office buildings reported hearing gunshots . Bystanders hid in fear . Shemaiah Ofori-Attah and her husband , Edmund , at first thought the speeding black car and sirens were part of a motorcade . `` Then when we heard the gunshots we knew this was something serious , so we just dropped to the ground , '' she said . Danny Farkas , the Alhurra videographer , captured the scene . He said he had a fleeting thought that perhaps the driver had explosives in the car . `` I was surprised at the movie-like quality of what was going on in front of me , '' he told CNN 's `` New Day .
