Arias underwent a psychological evaluation at the Lower Buckeye Jail, which is routine for inmates under suicide watch, AZcentral.com reports. The Maricopa County Sheriff's Office transferred Arias back to Estrella
after doctors determined she no longer needed to be under suicide
watch, reports the website.
AZcentral.com reports that Arias spent five days in a psychiatric unit after telling a Phoenix Fox affiliate that she would rather die than spend her life in prison.
The 32-year-old was convicted last week of first-degree murder in the shooting and stabbing death of her on-again, off-again lover, Travis Alexander, at his suburban Phoenix home in 2008. The trial will enter a new phase on Wednesday, during which jurors will weigh whether or not she should be sentenced to death.
Arias' defense team argued that she killed Alexander in self-defense.
Maricopa County Sheriff Joe Arpaio told CBS affiliate KPHO that Arias will remain at Estrella "on closed custody status." Authorities say she is held alone in a cell and allowed out for one hour each day for phone calls and showers.
The jury will recommend a sentence to the judge, who will make the final determination on Arias' fate.
