Arizona authorities arrest suspect behind threats made to TV anchors over Arias coverage
PHOENIX -- Newscasters Nancy Grace and Jane Velez-Mitchell were identified as the victims of online threats that Arizona authorities say a David Lee Simpson made because he was upset with their coverage of the Jodi Arias trial.
MCSO Sgt. Brandon Jones said Simpson was arrested and booked into the Fourth Avenue Jail on Wednesday evening. When authorities searched his car they found guns, ammo, handcuffs and other items.
Simpson, 48, was arraigned Thursday. He later told authorities that he had several pipe bombs in place in a rural area of northern Pennsylvania.
Simpson was previously indicted in Arizona on three counts of computer tampering and two counts of stalking.
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 said the anchors were identified because a news organization had already named them.
Arpaio said Simpson, of Bath, N.Y., was infatuated with Arias and became upset with Grace and Velez-Mitchell's comments about the case.
