In NYC, it was her sister. It was reported by the NY Post.
A few months ago, Carey was visiting her sister, had some sort of breakdown, and was taken away by EMS while restrained on a gurney.
The incident was corroborated by neighbors.

HARTFORD, Conn. (AP) — The sisters of a Connecticut woman fatally shot by police in Washington after she tried to ram her car through a White House barrier said Monday she wasn’t delusional and suggest she may have been fleeing danger.
The two sisters of Miriam Carey, who was killed Thursday with her 13-month-old child in her car, disputed the accounts of officials and their sister’s one-time boyfriend that she was under the delusion that President Barack Obama was communicating with her.
“What I do see is that perhaps maybe my sister was a little afraid being surrounded by officers with their guns drawn,” Valarie Carey said in an interview on NBC’s “Today” show. “My sister was fleeing. She was trying to figure out how to get out of there.”
The other sister, Amy Carey-Jones, suggests police overreacted or were negligent.
“I feel that things could have been handled a lot differently,” she said. “We still feel that there was maybe another story than what we’re being told.”
Valarie Carey said officials’ descriptions of her sister are “not the Miriam we knew.”
“She was not walking around delusional, which is what we really want the public to understand,” she said.
