Authorities continue to search for pipe bombs a Bath man claimed to have dumped in an Athens, Pennsylvania area waterway before he set out to kill two national TV commentators over their coverage of the Jodi Arias trial.
David Lee Simpson is jailed in Phoenix on five felony counts related to Twitter death threats against Nancy Grace and Jane Velez-Mitchell, both hosts of shows on the HLN cable network who regularly covered the nearly five-month trial and focused heavily on Arias' guilt. Authorities say Simpson told them he was in love with Arias.
An Arizona grand jury indicted him July 18th on three felony counts of computer tampering and two counts of stalking. Maricopa County authorities say he told them he was on his way to kill Grace when he was arrested in Bath. Investigators say the 48 year old also threatened a Phoenix woman via Twitter.
After his arrest and extradition to Arizona, authorities said Simpson indicated that he had placed several pipe bombs in rural northern Pennsylvania, but police knew of no connection to the explosives and the Twitter threats. Bomb-sniffing dogs checking Simpson's two cars in Bath indicated the presence of explosives residue.
Simpson is being held in a psychiatric unit with his arraignment set for Thursday.
