Sheriff Joe Arpaio explains a typical meal served to convicted killer Jodi Arias and all the other inmates at the Maricopa County Sheriffs Office Estrella Jail, during a news conference, on May 16, 2013, in Phoenix.

Jodi Arias has spent the past four years in cell B403 of the Estrella Jail in Phoenix. The room is located in the maximum security section of the jail, offering only the basic necessities – including a toilet - for 23 hours a day. She has been able to maintain an active presence on Twitter because when she speaks to friends on the phone, she will ask them to tweet on her behalf.

Sheriff Joe Arpaio showed her cell and its belongings to reporters, and said “I’m not going to ask her for her permission, I run this hotel. She doesn’t."

Arias receives one “sack lunch” and one “hot meal” each day, totaling 2600 calories.
