A woman accused of trying to kill Barack Obama with a homemade bomb was caught when she sent another explosive to a US governor with her own address scribbled out on the package, it is claimed.
Julia Poff, from Houston, Texas, is due to stand trial to face allegations of sending three homemade bombs to targets including the then-President last year.
According to court documents the 46-year-old was traced because a similar device sent to Texas Governor Greg Abbott , which failed to explode when he opened it, was in an envelope recycled from an eBay order.
Prosecution papers also state that cat hairs found on the package sent to Obama contained cat hairs which matched one of Poff's pets.
The bomb sent to Obama was 'rendered safe'.
Her third target, it is claimed, was Social Security Administration Commissioner Carolyn Colvin.
She allegedly targeted Colvin because she was angry about not being supported by the agency or her ex-husband.
Describing the bomb sent to Mr Abbott, the documents state: "Had the device exploded, it could have caused severe burns and death."
The package had an 'obliterated shipping label' with Poff's name and address on it, investigators say.
Pyrotechnic powder was found when authorities searched her home, prosecutors say, and FBI agents discovered animal hair on the package sent to Obama.
The prosecution papers state: "Cat hair was found under the address label. The hair was compared to two of Poff's cats by the FBI crime lab.
"The cat hair found on the Obama Package was microscopically consistent with the hair of one of Poff's cats.
"The case agent testified that Poff had stated that she did not like the President."
Poff has been charged with transporting explosives with intent to kill or injure, as well as fraud of the SNAP food stamps programme and making a false bankruptcy declaration.
She has pleaded not guilty and is due to stand trial in January.
The defendant was remanded in custody until then as the judge in the case considers her a potential flight risk.
