PHOENIX — Authorities were providing security Friday for the sole juror who voted to spare the life of convicted murderer Jodi Arias.

No threats had been reported against any of the 12 jurors, authorities said. However, the lone holdout on the death penalty had requested the security after her name was posted on social media.

Prosecutors also said they’re examining whether the holdout disclosed that her husband had been prosecuted by the same county attorney who headed the case against Arias.

The 2013 trial of Arias became a global sensation with its revelations about her sexual relationship with the victim and that she had slit his throat so deeply that he was nearly decapitated.

She was convicted of murder but that jury deadlocked on her punishment.

Prosecutors say Arias killed Travis Alexander as revenge because he wanted to date other women and was planning a trip to Mexico with his latest love interest.

The name of the holdout juror in the sentencing retrial was leaked through a Twitter account that also posted sympathetic comments about Alexander.

Meanwhile, a pro-Arias website published names of 11 people it said were the jurors who voted to sentence Arias to death for the 2008 killing.

A mistrial was declared Thursday and a judge will sentence Arias on April 13 to life in prison or life with the possibility of parole after 25 years.

Arizona law prohibits the public release of juror names. It’s unknown how the identities were leaked, but information appeared online after jurors who favored the death penalty expressed frustrations over the holdout.

Juror Emily Cova said she was relieved to hear that authorities were looking into the leak.

“I was a little nervous last night. But I’m feeling better now,” said Cova, who agreed to be named.
