PHOENIX — Convicted murderer Jodi Arias will have to go without phone calls and video chats in jail for now unless they have to do with legal matters, the Maricopa County sheriff said Thursday.

Sheriff Joe Arpaio said that Arias was trying to avoid having conversations monitored by using other inmates to make phone calls for her. She also is accused of speaking with minors through the jail’s video visitation system.

“Arias needs to understand that while she is in my jail, she is to obey all the rules and breaking them has consequences,” Arpaio said in a news release.

Arias was convicted of murder in Travis Alexander’s death at a 2013 trial that became a global sensation.
