PHOENIX (AP) -- Newscasters Nancy Grace and Jane Velez-Mitchell were identified as the victims of online threats that Arizona authorities say a man made because he was upset with their coverage of the Jodi Arias trial.

Maricopa County Sheriff Joe Arpaio said earlier this week that he wasn't going to release the anchors' names because Turner Broadcasting had asked that they be withheld.

But Arpaio released a statement Wednesday that identified Grace and Velez-Mitchell as the target of the threats made on Twitter.

The sheriff's office says the anchors were identified because a news organization had already named them as the victims.

Arpaio says 48-year-old David Lee Simpson of Bath, N.Y., was infatuated with Arias and became upset Grace and Velez-Mitchell's comments about the case.

When Simpson was taken into custody he reportedly had guns, ammo, zip ties, and handcuffs in his vehicle.

Simpson was subsequently extradited back to Arizona, and was booked into a Phoenix jail on Wednesday evening.

According to MCSO, on his flight to Arizona Simpson told authorities that he had placed three pipe bombs in a Pennsylvania river.

Authorities are now trying to locate those bombs.

Simpson has been indicted in Arizona on three counts of computer tampering and two counts of stalking. He could also face additional charges.
