Jodi Arias' prison cellmate says the convicted murderer threatened to have people "on the outside" kill prosecutor Juan Martinez and seriously questioned why he didn't love her.
Cassandra Collins, who shared a two-bunk cell with Arias before her murder trial told MyFoxPhoenix.com that if she got the death penalty, she would take revenge against Martinez.
"He need(s) to get good security staff around him to make sure she can't get anybody on the outs(ide) to solicit something -- to harm him or to hurt him. She's very dangerous -- very dangerous," Collins said.
Arias was convicted of murder in May in the 2008 death of boyfriend Travis Alexander in his suburban Phoenix home. Jurors failed to agree on her sentence, setting the stage for a second penalty phase.
Collins told the station Arias tried to "manipulate" other inmates into believing her side of the story. When she visited her jail area in January, all of her cellmates reportedly had signs reading, "Jodi is innocent" and "Free Jodi."
The Maricopa County Attorney's Office told MyFoxPhoenix.com it was looking into Collins' claims.
Meanwhile, Arias' attorneys said Tuesday want a judge to compel jurors in her penalty phase retrial to reveal their Twitter user names so the accounts can be monitored to ensure they aren't communicating about the case.
During a hearing, defense attorney Kirk Nurmi argued that Arias needs juror Twitter accounts to ensure they are not being influenced by outside elements. Martinez has called it an invasion of juror privacy. The judge hasn't ruled.
Judge Sherry Stephens is banning live television coverage of Arias' sentencing phase retrial as prosecutors again seek the death penalty.
