Maricopa County Sheriff's officials say Arias is back at the Estrella Jail where she will be housed until her trial has concluded.
Arias was convicted of first-degree murder on Wednesday in the June 2008 killing of her one-time boyfriend. She claimed she killed Travis Alexander in self-defense after he attacked her, but authorities said it was a planned murder fueled by jealousy.
She returns to court Wednesday as jurors determine whether the death penalty should be an option for sentencing. Arias could also face life in prison.
Authorities say she is held alone in a cell and allowed out for one hour each day for phone calls and showers.
