PHOENIX, Arizona -

 A judge has denied a motion from Jodi Arias' defense team to have the death penalty removed as a sentencing option.

In court documents filed Friday, Judge Sherry Stephens says Arias' attorneys showed no evidence that banning a defense aide from making jail visits last March prejudiced the murder case.

Maricopa County sheriff's officials say mitigation specialist Maria De La Rosa was banned for a week after she took a drawing by Arias out of the jail.

Stephens says there's no proof that the incident would impact the ability to present evidence at Arias' penalty phase retrial in September.

Arias, a former Palm Desert resident, was convicted of first-degree murder last year in the 2008 killing of her lover, but jurors couldn't reach a decision on sentencing.

Defense attorney Kirk Nurmi declined to comment Saturday.
