Julia Poff, 47, pleaded guilty in a Houston federal court Monday, to transporting explosives with intent to kill, injure or intimidate

A Houston-area woman has admitted she addressed package bombs to former president Barack Obama, Texas Gov. Greg Abbott and the Social Security Administration.

Julia Ann Poff pleaded guilty in Houston federal court Monday to transporting explosives with intent to kill, injure or intimidate.

Although the plea related directly to the package she addressed to Obama in October 2016, prosecutors say the 47-year-old Brookshire woman's plea deal also acknowledges mailing similar packages to Abbott and the Social Security Administration.

All of the packages contained improvised booby traps that postal authorities intercepted and rendered harmless with no injuries.

She was caught after the FBI managed to trace microscopically small amounts of cat hair that were found inside the envelopes - and managed to identify them to have come from Poff's own cat.

Poff could be sentenced to up to 10 years in federal prison and fined up to $250,000. She will be sentenced in November

Investigators say she admitted she didn't like the former president, while she is believed to have sent explosives to Colvin and Abbott because of the way the state dealt with her child support case.

Cops said that the amount of explosives hidden inside the packages had the potential to cause 'severe burns and lots of severe injury and possibly death.'

The packages for Obama and Colvin were screened by security and rendered safe but Abbott opened his personally. Thankfully, the explosives did not detonate because 'he did not open it as designed.'

His package contained a small box with explosive pyrotechnic powder used in fireworks, a hobby fuse and a small plastic cap filled with the same type of 'lead shot' found in shotgun shells.

A third box addressed to the head of the Social Security Administration was sent in October 2017, after she was denied Social Security disability benefits for the third time.

Investigators were able to catch Poff after tracking the packages back to a mail drop box in Brookshire, just outside of Houston - the town Poff calls home.

Cat hair found in the packages, along with a USB cable box, debit card purchases and Poff's brand of cigarettes led them to her door.

Investigators found cat hair under a taped address label, 'microscopically consistent' with hairs taken from Poff's gray cat, named Ash.

Poff’s daughter also told authorities that the phone in the box was her old cell phone, which she had last seen in August 2016 in their home’s garage according to the Houston Chronicle.

When searching her home, they discovered fireworks and reloading equipment, as well as a pair of latex gloves.

One of Poff's previous jobs was working at a fireworks stand for years, investigators added.

She was also found to have told witnesses in a Facebook post not to cooperate with the FBI and to tell her what questions had been asked, according to court documents.

'Julia posted on the group, 'If the FBI tries to contact anyone, don't talk to them and let me know you've been contacted,'' an investigator said.

Poff could be sentenced to up to 10 years in federal prison and fined up to $250,000. Sentencing has been scheduled for November 18.
