The drama began around 2:20 p.m., officials said, after Carey — driving a leased black Infiniti — sped into the driveway leading to the White House and tried to breach security at the intersection of 15th St. and Pennsylvania Ave. NW, officials said.
Thwarted by the concrete barriers and confronted by cops with their guns drawn, Carey spun the car around and hit the gas — knocking a Secret Service agent over the hood of the car as she sped away.
At speeds of up to 80 mph, Carey sped 12 blocks toward the Capitol as she was chased by Capitol Police and Secret Service agents.
At Garfield Circle, Carey raced through the first hail of bullets.
At Constitution Ave. and Second St., she rammed a Capitol Police car “and then barreled into some barricades outside the Hart Senate Office building” where she was surrounded by police and Secret Service vehicles, blocked in, and shot by police.
While initial reports indicated that Carey had fired shots, ABC News reported that police said “no weapons were found in the car.”
Miriam’s mother, Idella Carey, told ABC News that her daughter “had postpartum depression after having the baby” in August 2012.
“A few months later, she got sick,” Mrs. Carey added. “She was depressed. She was hospitalized.”
Police confirmed that Miriam’s one-year-old daughter, Erica, was taken from the car and put in "protective custody."
The Daily Mil reported that Carey grew up in Brooklyn, New York.
Ruth Macon -- a neighbor of her sister, Amy Carey -- said the sisters didn’t get along.
“They just don't see eye-to-eye.”
The Washington Post reported that Amy Carey, a Brooklyn nurse, “had no idea why her sister would be in Washington.”
That's impossible. She works, she holds a job. She wouldn't be in DC. She was just in Connecticut two days ago, I spoke to her... I don't know what's happening. I can't answer any more.
While Idella Carey told ABC News that her daughter had "no history of violence," she also didn’t know why her daughter was in Washington, D.C.
She thought Miriam was taking Erica to a doctor's appointment in Connecticut.
Dr. Steven Oken, Carey’s former boss of eight years, described her as a "non-political person" who was "always happy."
I would never in a million years believe that she would do something like this. It's the furthest thing from anything I would think she would do, especially with her child in the car. I am floored that it would be her.
However, Carey’s last employer, Dr. Brian Evans -- a periodontist whose practice is in Hamden, Conn. -- told New York Daily News that she “had a temper, and he recalled how she became incensed when he asked her to quit parking in a handicapped spot at the medical building.”
She got very angry with that, so that started some friction. And then from there she was never insubordinate per se, or anything like that, but she tended to go against the grain a bit.
Evans also said Carey once “fell down some stairs and she had a pretty significant head injury.”
It was while Carey was in the hospital that she discovered she was pregnant and – according to Evans – “seemed happy.”
While Evans let Carey go last year, he said “it was nothing related to any mental problems that we were in tune to.”
Following Thursday’s incident, police -- including SWAT and bomb disposal units -- surrounded the apartment complex in Stamford where Carey lived. As police waited for a search warrant from Washington, 50 other tenants were evacuated for the night.
One of Carey’s neighbors, Erin Jackson, said she believed Carey lived in the Stamford home with the baby and the girl's father.
They were not married.
Asked if she believed Carey suffered from a mental illness, Jackson said "absolutely."
But The New York Daily News quoted Carey’s 46-year-old neighbor Jeff Newsome – who described Carey’s boyfriend as a “heavy-set guy in his 40s” – said “she seemed like a nice young lady, stable.”
The Washington Post reported that Angela Windley -- a 33-year-old woman who “befriended Carey while both attended Hostos Community College in the Bronx, New York City” – said Carey moved to Stamford after having "some problems with her landlord."
"She wanted to have a better life," Windley said. "The neighborhood we both grew up in wasn't the greatest, and she always talked about getting out."
But the Brooklyn rents were getting so high when she looked at a new apartment that she thought she would try to buy a condo or a co-op, that’s how she landed in Stamford.
While Windley said she hadn’t seen Carey in recent years, Carey hadn’t shown signs of mental illness during the time Windley knew her and “was not one to even talk about politics.”
However, Windley did say Carey could come across as “arrogant” and didn’t have many friends.
If there was a negative, people said that was it. She could be sort of conceited, like she knew everything.
As Juliet asked famously in William Shakespeare's Romeo and Juliet: "What's in a name?"
"Miriam" -- Hebrew in origin -- means "uncertain, maybe bitter."
As The Daily Mail noted further, “the revelation by Miriam Carey's family is the first hint at what could have caused the dental hygienist to drive her Infiniti luxury sedan 270 miles from her home in suburban Stamford to Washington, DC - where her rampage put the nation's capital on lock-down Thursday."
On Sept. 16, a partial lock-down was enacted in Senate buildings when Aaron Alexis -- another 34-year-old who “had a temper” and a history of mental illness -- shot and killed 12 people and wounded eight others at the Washington Navy Yard before being shot dead by police.
